Spyderco Ayoob

 “Captain, she’s phasing.  I can’t stop the dilithium drive occultations.  We’re entering intercostal space!”

Don’t worry, the brilliant chief engineer and intrepid captain, with the help of a beautiful alien female scientist, will solve the problem. 

Let’s be real.  Intercostal space is the distance between ribs.  Around 2001 Massad Ayoob designed a folding knife to fit between the ribs and lacerate the heart.  The design locked the blade open at an angle of less than 180 degrees.  This allows you to utilize the knife with the wrist very close to the strong, neutral position.  More on that later.  Spyderco has re-issued it as a sprint run.

Stolen from University of Nottingham - Note the heart and intercostal space.

 The original was produced as both a fully serrated and plain edge with a black Almite handle and a blade made from VG-10.  Almite is a surface coating used on aluminum for decorative and protective reasons.  It is available from “super hard” to “soft” with differing Vickers hardness.

The Ayoob sprint run. The handle is a lighter gray.

VG-10 was initially produced for Japanese chefs.  Its properties soon caught the attention of other knife companies.  Spyderco was not the only one to utilize this steel.  Kizer, SOG and Fällkniven are among VG-10 users. 

By the way - - if you aren’t reading this at “The Knife Edge: One Man, So Many Knives,” it has been stolen and used without my permission.  Please let me know at Frank1karl@yahoo.com.

Years ago, Joyce Laituri told me Spyderco didn’t like making knives whose sole purpose was to harm people.  But they would if agencies requested those designs.  The Ayoob was in the 2001 and 2002 catalogs but disappeared in 2003.

Note the angle between the blade and handle.

Despite the short run, the Ayoob knife picked up a vocal following and Spyderco has brought it back as a sprint run.  I really like mine. 

The current Ayoob C60GPGY has a G-10 handle over steel liners.  The scales are set up so you can move the pocket clip to facilitate your favorite carry method.  The clip holds the knife slightly visible in your pocket, an important consideration for anyone concerned about concealed weapons.  The visible portion of the knife eliminates the concealed aspect.  A David Boye release lever is incorporated to reduce the possibility of your grip accidentally unlocking the knife.  I don’t believe there are any actual documented cases other than those few that were engineered to demonstrate the potential.

The steel used on the sub-four-inch blade is CPM CRU-WEAR.  It is an interesting steel, but you should know its limitations.  The elemental composition gives it better wear properties than D2 tool steel, better toughness than M2 steel, and more compression strength than either.  The properties of any metal are essentially a teeter-totter.  Raise one property and another property sinks. 

CRU-WEAR has only 7.24% chromium.  The steel’s carbides are primarily produced by 2.4% vanadium and 1.6% molybdenum.  These tiny carbides are more of a ceramic particle, very hard, and they pin grain boundaries preventing movement.  

With less chromium bound up as carbides, more chromium is available for corrosion resistance.  Unfortunately, CRU-WEAR is not a stainless steel.  The chromium levels are too low, and Spyderco warns you about that.  I’d avoid cutting acid fruit and vegetables, as the acid content will attack and stain the blade.  This could be good news to the ketchup patina fans out there. 

The choice of steel utilized by any manufacturer can be a rabbit hole exercise in futility.  Sometimes it’s market pressure to keep up with the other guys.  Sometimes the steel you prefer is no longer available for various reasons.  Sometimes it is just a way to keep your staff engaged.  Joyce once commented that Spyderco sometimes acts like a small independent maker and tries new steels to stay fresh.  It makes it hard on Spyderco collectors, but I like it. 

So what makes this fighting knife special? 

There are several things.  The first was already mentioned.  The blade is designed to fit between the ribs and penetrate deep into the chest cavity, lacerating lungs, heart and other vital structures. 

Deep penetrating injury.

Perhaps the most notable feature and innovation is the angle between the blade and handle.  I’ll let Massad Ayoob explain it.  "With a typical knife, thrusting lifts the blade's point above the line of the forearm, like a boat prow going through water. The faster, harder or more resistance encountered, the higher the prow rises deviating the blade off course from its original target which can mitigate the depth of the cut.” 

What Ayoob doesn’t explain, Jim Davis does:  “Regarding wounds, stab wounds are far more prone to kill a person than slash wounds.  Stabs tend to penetrate and hit arteries and organs, causing internal bleeding.”  http://tactical-talk.blogspot.com/2021/01/jim-davis-on-knives.html

 

When you are fighting for your life, severe measures are called for.

The blade/handle angle allows your wrist to lock into its strongest position, which we call the neutral position.  The medical terms for the positions associated with a bent wrist are adduction, extension, and flexion.  The joint loses strength when your wrist is in these positions, even if not at the extremes.  The Ayoob Clipit lets you cut and stab with your wrist in the neutral position.

Spyderco's Endura with the wrist in neutral position. The blade tip points upward.

 

Spyderco's Endura with tip canted to engage target.  Note bent wrist, compromising grip.

Spyderco amplifies these ideas, stating:  “The C60's radical angle brings the blade into line with the long bones of the forearm, channeling the body's force directly behind the line of the cut resulting in minimized blade deviation and maximized accuracy.”

 

Spyderco's Ayoob on target neutral and strong grip position.

Any knife will open your mail and packages, cut cordage, and slice pizza.  Many of these knives will end up as Safe Queens, only seeing the outside on special occasions, holidays and barbeques when you want to show off the knife.  

That’s okay.  This is a special-purpose knife.  I remember listening to a British WWII commando explain how to properly use an F-S fighting knife.  You couldn’t use the Ayoob C60GPGY for that.  You wouldn’t want to use it to split kindling to build a fire or to saw through a can top when you lost your opener in the back forty acres of nowhere. 

Lastly, who is Massad Ayoob, and why should his ideas be put into production?  Google his name, will you?  Anything I write would sound like hero worship.  I admit, he’s a pretty cool guy and someone you want on your side when you’re getting into trouble or trying to survive the aftermath. 

The Spyderco Ayoob is a limited sprint run.  I find the Ayoob C60GPGY an attractive knife.  You’ve been warned.  They’ll run out fast.

Might be the right backup weapon.

Mickey's Knife

 In an effort to get ahead of my summer fitness cycle, I have started walking with a 15 pound backpack.  I chose a single sling pack from Maxpedition with my special attachment, one of Boker’s collaborations with Mickey Yurco.  It is called The Pocket Knife.  The Ulticlip allows you to clip it inside a pocket making it easy to carry and access a fixed blade.

Boker's Pocket Knife on my pack

I like the knife.  The elongated egg-shaped handle is depressed by about 26 degrees from the center blade line.  This allows the knife to be held in a neutral wrist position.  This is perhaps the strongest, most stable position for your wrist when holding a tool.

The blade isn't quite so long, all due to accidental camera angle magic

Two knives held in the same position with my wrist at the neutral angle. The Boker extends outward more aggressively

We are, after all, tool-bearing mammals and a knife is just a tool.

The blade is a graceful saber grind drop point blade tapering to a point made from 440C stainless steel.  It is 3.3 inches long with a 0.15 inch thickness and the overall length of the knife is 6.8 inches. 

The handle is constructed of black G-10 and has a slight palm swell making it easy to grip.  The finger detent in the steel and the palm swell make gripping this knife easy and comfortable.  It is in the running for the easiest and most comfortable using knife I’ve ever owned.

The Kydex sheath

The Kydex sheath secures the knife upside down and close to the body.  I don’t have to worry about bushes or brambles plucking at my knife in an effort to detach it.  The Ulticlip lets me clip the knife on the padded shoulder strap about the middle of my chest.  This is just about where a surprise or fear reaction instinctually brings the hands to.  The clip allows almost instant removal should I need to move the knife and sheath to a different location.

Why a knife?  Because sometimes I can’t get to a firearm fast enough.  If I had a dime for everyone who told me they would simply draw their blaster and shoot their knife/club attacker I would be a rich man.  While a subject for a different blog, attacks are usually done by surprise, without warning, and with a high level of violence.  Awareness is the key to survival, followed by having a tool and skill with the tool.

The Ulticlip allows you to move the knife and sheath from location to location quickly.  

If you are not familiar with Boker, or only think of the lower spectrum of their knives, think again.  Boker makes some very high and middle-level knives at reasonable prices and excellent quality.   Mickey has at least two knives in the Boker catalog.  I find the Yurco Pocket Knife one of my favorites.

Boker's Pocket Knife

Mickey Yurco is an interesting fellow.  He’s been making knives for a number of years and has a number of unique concepts.  His current creation is a fixed blade knife he and Boker Knife call The Pocket Knife. 

Mickey's fixed blade "The Pocket Knife"

The first thing you notice when you open the box is the graceful saber grind drop point blade tapering to a point.  The egg-shaped handle is depressed by about 26 degrees from the center blade line.  More on that later.  The handle also sports a cutout that accommodates your index finger.  The egg-shaped handle is constructed of black G-10 and has a slight palm swell making it easy to grip the knife.  The upshot of this design is a knife that locks into your hand and the allows your wrist to be at its neutral position where you have the most strength and control of the knife.

Clearly it was a designed for a purpose. 

Let’s look at the specs, shall we?

The knife is made from 440C stainless steel.  The blade is 3.3 inches long with a 0.15 inch thickness and overall length of 6.8 inches.  The finger groove acts as a stop to keep your hand off the sharp edge.  The bend also helps to keep the knife from slipping forward or backward in your hand by converting either motion to a push into your palm or a press into your closed hand.  A large lanyard hole is available, always a good idea when working over water or deep snow.  

The knife seems to want to nessle deep into the palm of my hand

440C isn’t a super steel.  But it is the best of all the 440 steels.  It is also the steel everyone compares their newest steel to.  Frankly a well-made, well-tempered knife of 440C will give you all the performance the majority of us will ever need.

No discussion of steel is complete without a formula sheet:

440C contains:

• 0.95-1.2% carbon
• 16-18% chromium, 
• 0.75 molybdenum,
• 1.0 manganese and
• 1.0 silicon.

 This formulation provides high strength, moderate corrosion resistance and good edge retention.  Some of the chromium and carbon form tiny carbides on the grain boundary.  Iron also can form carbides, but they are not as effective as chromium carbide.  These grains are very hard and resist the shear needed to displace the steel grains.  This is what gives steel its strength.

The remaining chromium forms a transparent thin film of chrome oxide that limits rust making the steel discolor or stain less.  Still an occasion drop of food grade oil is always a good idea.

The results of this chemistry and heat treatment gives The Pocket Knife a Rockwell hardness c scale of 57-58. 

The sheath is made from strong light weight kydex

The sheath is fabricated out of kydex and sports what I think is a unique attachment device, the Ulticlip.  This clip allows you to fasten a variety of holsters and sheaths to pants without a belt.  The sheath slips into your pocket and locks on to the edge and provides a secure platform to draw the knife.  The knife sheath is designed so you can set it up for left or right pocket carry.  Mine arrived set up for left side.  I may leave it that way.

The Ulticlip is relatively new but quickly becoming a go-to solution for anchoring whatnots

The way back story.

Mickey has been seriously studying martial arts since the early 70s.  By 2000 he became interested in knife combatives as taught in Martial Blade Concepts.  Despite being in law enforcement, Mickey realized that even with CCW not everyone can carry a firearm, but most of us can carry a knife.  Mike Janich has developed an evolving concept of using a small legal knife for self-defense.  These concepts were attractive to Mickey and evolved into “The Pocket Knife.”  I’ll let Mickey tell you about it.

The wrist is in the neutral position and aligned with the long bones of the arm for maximum strength. 

“It was designed to be carried to the far right (just like my politics) of the front right pocket.  A fixed blade can be drawn and deployed faster than a folding knife.  Picture a normal stance with your thumbs in your pockets.  Your hand is now on the knife handle.  It is an inconspicuous way to quickly unsheath the knife. The small egg shaped handle fills the air pocket in the palm allowing a good grip.  The small handle also stays out of the way when not in use. This little blade is also a great shape for everyday mundane tasks from opening mail to cutting a steak at the Outback.  An email I received from Boker stated that it was a popular knife at a German Knife show.  I am pleased with their interpretation of my knife.”

I thought the knife needed to be a little lower in my pocket, so I moved the clip up one notch.  I like it lower in the pocket.  Yes, I will probably scratch the G-10 handle, but as I see it as a tool, I’m okay with that.

Sharp out of the box

I also did a little cutting with mine.  Cut a little rope, reduced cardboard to smaller pieces shaved a little wood.  I think it would make a great pork chop knife.  I’d take it for a walk off the concrete, for weekend at a cabin, or just simply heading out.

I think it’s a pretty cool knife.  Spend 5 minutes with Mickey and you’ll see how dangerous a knife can be in trained hand.  But even I know, that going up against someone with a couple inches of sharpened steel in their hand makes most people think twice.

You can get one for yourself for $60.00 at Boker.  Just follow the link: https://www.bokerusa.com/pocket-knife-02bo522

Provoke

A recent episode of the “The Rookie’ shows one of the characters showing his last resort knife to his training officer.  It resembles a Benchmade 175BK push dagger.  It’s a short story arc that helps support the longer main arc.   

Still, one can see why real LEOs will carry a last resort weapon.  They don’t have a room of script magicians to write them out of the problem.  These weapons are usually very simple to use.  Any tool that requires year to learn and five years to master will fall outside the definition of ‘tool-of-last-resort.’

Karambits have this tool potential.  The ordinary user can slip his little finger onto the loop and hold it in a hammer fist and simply claw his way out of danger trouble.  Placing your thumb on the back of curved spine will give you a little more feedback.  Are we not trained to touching things with our thumb?  The same almost autonomic reflex helps guide the blade.

Held in the reverse grip, the blade juts out of our fist like a prehistoric claw, perfectly situated for close infighting moves. Small wonder folding karambits are so popular.  Closed, they are easy to conceal, a basic impact weapon and open, it becomes so much more.

In the hands of someone with more training than I, the karambit has multiple applications.  The dull spine can be used use to trap and control opponent’s arms and balance, making a range of other physical responses available.  The razor edge lets you transition from physical control to higher levels of force almost instinctively. 

Folding karambits have some problems.  Opening isn’t always easy and fingers can get in the way of the edge.  Lock and pivot points wear and fail from applying load on the spine or side of the blade.  All knives direct the load into the handle but the twisting load generated by using the blade as a control device can cause handle failures.

CRKT's Provoke, designed for LEO and people in dangerous places

Many of the devices used to open the blade as you remove it from your pocket don’t assist you opening the karambit if you are holding it in your hand as an impact tool.

CRKT has taken Joe Caswell’s design and produced the Provoke.  It is a unique knife that may change how we open and close folding knives.  Your fingers are never in the path of the blade when opening or closing.  The blade is firmly locked in place by two stout arms.

The front of Joe Caswell's innovative folding karambit 

The problem is opening from the pocket draw.  The optimal opening has the index finger through the ring and the dull spine against the palm of your hand.  The thumb presses the back pivot point and the blade pops open.

Back side of the Provoke.  The clip holds the knife deep in the pocket.  What you see doesn't look like a clip.

Here’s a right and left hand draw with opening showing the finger movements I use.  It looks clumsy when shone slowly to reveal finger movement.  It’s not.  Practice for ten minutes and it will feel completely natural to you.

Left side opening.  I needed to pivot out of the camera view to show the opening.  You really don't hold it like a soiled tea bag. 

Right side opening.  The knife must slide from the thumb to the index finger

It’s not an inexpensive knife and has limited general application.  Its cutting edge design and manufacturing has built in a high degree of reliability.  It is last-chance-tool to claw your way out from under the casket lid.

Teach Your Daughters To Hit

Teach Your Daughters To Hit Someone Who Touches Them

Assault

I recently read this article on http://www.breachbangclear.com/teach-your-daughters-to-hit-someone/

It’s one of my favorite blog/websites.  I’m reposting because I believe in what it says and I feel it has value to the community.  I do have a few remarks and here they are:

Many of the readers responded that in many school systems it’s a felony to use violence, even in self-defense.  That this record could follow you and prevent you from joining the military, getting clearance or a job.  Others point out that jobs and some schools have policies that require your immediate dismissal.

I believe this is empowers the creeps who know the treat of dismissal or a felony charge will make their victim complacent.  One only has to look at the Hollywood-Harvey Weinstein scandal to understand this.  I can’t change the world, but we can by insisting our schools and place of employment treat self-defense is a right and not an option to be conveniently discarded.

I’m clearly on the kick ‘em in the nuts and break their fingers side and I if I had a daughter (or son for that matter) I’d tell her what David says and that we’ll find a solution for the aftermath later.

David Reeder:

“Teach your daughters, goddaughters, and nieces to fight. If you can’t, then pay someone to, and teach them that violence is acceptable. Teach them to hit people who touch them. Not tell the teacher, not complain to the Human Resources department, to hit them, as viciously as possible, immediately and publicly.

Testicles, throats, eyes — they’re all vulnerable.

Violence may not always be the answer, but when it is the answer, it’s usually the only answer. Including when, perhaps especially when, someone touches them without permission.

Speaking strictly to my nieces and goddaughters, I say: you bring me the scrotum of some dude who grabbed your boob or your butt, girls. I’ll reward you and turn it into a tobacco pouch.  I’d hold forth and talk more about this, but Jeff Rouner of the Houston Press already has, and he did a great job of it.

http://www.houstonpress.com/arts/i-dont-mind-telling-my-daughter-to-fight-back-physically-when-assaulted-9918363

Jeff Rouner:

“I’ve started telling my daughter that if someone touches her chest, her ass or between her legs without her permission, to punch them in the goddamn face. Aim for the nose, Sweetheart. You don’t want to catch their teeth and get a cut. That’s a good way to get an infection. You want nose or eyes, and maybe use that front choke Daddy taught you. Turn your forearms so the bone goes against their carotid and jugular. That’s what makes them pass out.

Can she get in trouble for violence at school? Yes, she can, and should. Violence is illegal. Note: I didn’t say wrong. I said illegal. The two are not synonyms.

[…]

Is violence the ideal answer to sexual harassment? Of course it isn’t. The ideal answer is living in a world where this sort of thing is swiftly dealt with at all levels of authority with a zero-tolerance policy. Anytime y’all want to make that happen, you let me know. Until then, I’m teaching my daughter the proper way to throw a punch, and if you don’t like it, teach your kids the proper way to act.

Answering physical assault with physical assault is perfectly appropriate, and I have long since stopped caring about the concept of polite when it comes to those who feel boundaries are optional….”

David Reeder:

“Fuckin’ A.”

So there you have it.  Personally I suspect that no school or business wants the publicity what would come from institutionalize sexual violence by prohibiting self-defense.  My experience is organizations suddenly go silent when you offer to take it to the press.

Tiger, tiger....

Karambits are popular right now for a variety of reasons.  Like so many weapons from South East Asia, they trace their origin to some animal attribute or farm implement.

And why not?  Nature shaped a bears claws for specific purposes, just like the teeth of a shark.  If you need to accomplish a similar purpose, starting with successful examples is not a bad idea. 

It should be self-evident that all invaders strip the conquered of their weapons.  What does the resourceful farmer do?  He learns to defend myself with farm tools and everyday objects. 

I can almost hear the conversation: “Oh no Master, Officer, Governor, Police, that’s not a weapon, but two sticks chained together that I use to thresh grain so I can pay my taxes.  I’d never think of breaking bones and heads with it….”

The karambit or kerambit as it’s known in Indonesia, comes from humble beginnings as well.  It was an agricultural implement used to rake roots, thresh grain and plant rice.  Folklore claims it was inspired by the claws of a tiger.

Slip your little finger in the hole and slash.  Most of the blocks I know work really well with a karambit in one hand! 

Wikipedia has a romantic tale of Indonesian women who would tie a karambit in their hair for self-protection.  I like this tale as a karambit has been described as an instinctual weapon.  More than 15 years ago a self-defense instructor told me “…put your thumb on the back of the blade and simply wipe your thumb on your target.”  He was talking about a classic straight blade; the same applies to the karambit. 

I recently got my hands on a karambit from the We Knife Co.  We is a Chinese company that has been making knives for the last 10 years under the name Wayeahknife.  In 2014 they had the opportunity to expand and changed their name to We Knife Company. 

Their mission statement?  "Building the highest quality knives and tools and giving you plenty of choices in our products."  Sounds pretty good.  They’re using equipment like CNC machines, CNC grinding machines, precision stamping machines, as well as EDM machines to produce high quality knives which they sell in the US and Europe.  These knives aren’t aimed at the Chinese market, as locking blades are illegal.

My karambit is model 708A and the specs are pretty impressive.

The blade has a linear measurement of 2.8 inches, but the curved edge gives you more cutting surface.  The steel used is CPM S35VN with a Rockwell hardness of 59-61.  The blade rolls open on ceramic ball bearings.

We claims the blade is flat grind, but I believe it is better described as a saber grind.  The knife is a frame lock and the locking bar has what appears to be a small steel insert that wedges against the steel blade when open.  Many of the better aluminum and titanium knives utilize a steel insert to protect the softer metal of the locking bar from excessive wear from the back of the blade.  It’s a nice touch.

The handle, metal clip, metal screws and cap are all TI6Al4V.  This alloy is the most commonly used titanium alloy used outside of the aerospace industries.  Wikipedia claims “…. It has a chemical composition of:

• 6% aluminum,
• 4% vanadium,
• 0.25% (maximum) iron,
• 0.2% (maximum) oxygen,
• remainder titanium.  

It is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties.  Among its many advantages, it is heat treatable.  This grade is an excellent combination of strength, corrosion resistance, weld and fabricability.”

I like the flipper on the blade.  It really pops the knife open and serves as guard to prevent you sliding onto the blade.  I would have preferred the flipper to be used as an assist to open the knife as you draw it from your pocket.  I’m also disappointed the clip isn’t reversible.  The knife is set up for right hand, tip up carry.  It’s my favorite carry mode, but in everyday life the karambit might best be, as Doug Marcaida described it, as a “back-up weapon”.  The ability to adjust clip for your carry mode would have made this knife a much better product.

I know very little about fighting with a knife.  Watching someone who knows how to use a knife sends shivers down my spine.  But if you are like so many people who look at a knife and ask “Could I defend myself with that knife?” you should take a look at We’s karambit.  The answer is yes!

Spyderco vs.?????

The expression “It’s a poor knife that cuts only one way” has found its way, with some minor modification, into detective fiction, adventure romances, and science fiction, just to name a few.  I’ve even pointed out to students that a tactical flashlight points in both directions. 

But the Spyderco Civilian is a knife that cuts only one way.  It comes with a special note.

Here’s the text.  As an ‘abridger’, my apologies for any misrepresenting the sentiment behind Spyderco’s statement.  

“Spyderco has traditionally maintained what we call the “White Hat” position.  …that the future of mankind in the world must lie in cooperation and greater socialization.  …We recognize that a knife ... can be used (solely) to defend oneself…(but) we have never produced such an item.  Spyderco … caters to the law enforcement personnel on a worldwide scale.  They would be the good guys, or ‘White Hats’.  It has been requested that we … provide an effective last-ditch defense in assisting the “White Hats.”

The Civilian model is the first of several folding knives designed and produced as a law enforcement back-up defense weapon.  The Civilian model was not designed to kill. … It is designed to ‘hit and run’ in a self defense situation.”

I unwrapped the package and found, to my surprise, this collector-grade pouch.

While it’s true the Civilian isn’t designed to stab, it is designed to make an ocean cut.  With the reverse-S shape and the tremendously powerful Spyderco serrations, anyone you cut will be cut deep and wide.  It’s also well established that many effective targets on the human body are just under the skin.

The Civilian and its ilk (the Matriarch – versions 2 and Lil’) aren’t the only Spyderco folders that focus on the grittier side of self-defense.  The P’kal has very strong roots in self-defense as does the Yojimbo 2.  But only the Civilian was designed solely for self-defense.  It also comes with a tag that amplifies its purpose:  “Notice – This knife was not designed to be used as a utility knife.  Its unique design will not support everyday use…”

Why does Spyderco feel it’s necessary to include this statement?

I don’t know.  It could be legal preemptive boilerplate; maybe it’s an attempt to assuage personal feelings that such things are still necessary in this world.  Maybe it is guilt from knowing that no matter what you attempt or intend, someone will misuse it.

Let’s get to the Civilian’s specifications:

• Size closed                          132 mm*
• Blade Length                      104 mm
• Clip                                        Right side only, tip up or down
• Blade                                     Hollow ground VG-10
• Handle                                  Steel reinforced G-10
• Edge                                      Do you have to ask?  Spyder-Edge!
• Thickness                            10.4 mm
• Cost                                       I’m not sure how to answer that.  When push-comes-to-graveyard, what’s your life worth?  If you never need it, what’s it worth to have your grandkids inherit the knife and wonder what kind of freaky stuff were you into?  The more conventional answer is it retails for $280.
• 
  

The only Spyderco folder made specifically to cut human flesh.  The Civilian.

Do you need one?

This isn't a typical, "If I don't have one, I must need one" answer.

I just sold one to someone who, because of his job, will be going into dangerous surroundings.  Because of his job, he can’t take a firearm, nor will there be guards surrounding him.  He feels this knife might stand between the grave and his returning home. 

I, on the other hand, took his Civilian out of the soft-sided pouch it comes in and opened it.  The Spyder-Edge glittered like jewels set in silver.  The reverse-S blade has grace and flows outward from your hand.  The insulating G-10 is warm to the touch and the handle naturally finds a sweet spot in your grip.  My thumb, trained from decades of using Spydercos, found the hole without any thought on my part.

I made a few air cuts.  The Civilian almost seems to anticipate your movements before you do. 

It’s a work of art, lovely and f@^king scary as hell.

*Yeah, it’s metric.  The only four places in the world still using the English system are England, Liberia, Myanmar and the US of A.  Let’s get with it!

A 3-way: TOPS vs Ka-Bar vs Shadow Tech

Just about any knife can cut string or trim a coupon out of the paper.  But let’s get down to specifics.  There are knives designed solely for self-defense.  Not knife dueling, like Tommy Lee Jones and Steven Seagal in “Under Siege,” but an honest to Gawd cut-them-off-of-me defense.

The three I have in mind are Ka-Bar’s TDI knife, Shadow Tech’s QRT and TOPS California Cobra.

The first thing you notice is they’re all fixed blades.  Despite what you think or practice, rolling around and fighting for your life makes it difficult, almost impossible, to produce a folder, get it open and use it.  It takes practice.  A lot of practice.  A fixed blade makes that aspect so much easier.

The TDI knife is well known.  John Benner designed a knife that police could carry behind their magazine pouch.  The curved shape lets you stab and slice with the wrist in the neutral position.  This is a powerful position as the cutting edge is parallel to the long bones of the arm.   

 

Ka Bar's TDI Knife

It’s made in Taiwan but it’s a Ka-Bar so you know the quality is built in.  The curve and oval handle keeps the blade centered in your hand and prevents you from sliding forward on the knife. 

 

The reverse grip has become popular. Weak-side carry, draw the knife with weak-side hand, slice your way free.

It’s never a good idea to cut yourself when the chips are on the line.  It also works very nicely in a reverse grip.  Just drag your fist over anything that’s not you and it is cut. 

I picked up Shadow Tech’s QRT at this year’s Blade Show.  

'

Shadow Tech QRT.  That's Quick Response Tactics to you.

They were still smoothing out a few of the wrinkles but I recognized it’s coolness from a distance.  I only had to hold it to realize its potential.   

The Bowie style blade is almost perpendicular to the handle.  Again the wrist can stay in the neutral position and not be hyper-extended in the saber grip.  Hyper-extension of the wrist robs strength from the fingers. 

 

The oversize hole really gives you an almost unbreakable grip and the coarse jimping on the top provides plenty of grip surface for the thumb.  It’s another knife you won’t slide onto the blade if you stab into something hard. 

Trust me, this knife isn't going anywhere I don't want it to go.

Unfortunately the hole is too small for my hands in winter gloves.  There’s a little choil under the ring that can be utilized by the gloved index finger.  It’s right next to the blade so be careful and hope that between the glove and the handle jammed against the palm of your hand you will not get cut.  It’s a poor knife that only cuts one way, so a reverse grip can be utilized.  Again, just practice and learn to cut anything that’s not you.

TOPS California Cobra is a nasty little piece of work.  Oh, it’s quality and I’m sure it works just like they claim, but one look at it would be enough to discourage me.   

TOPS Cobra.  It almost hurts you to look at it.

The knife has three useful edges.  Useful to you that is, not the target.  One is a sharpened pyramid at the bottom of the guard.  TOPS calls it the sting, the less lethal option. 

 

Sharpened Steel Sting  Get the point?

I can imagine jabbing someone with it and convincing them they should let go and find someone else to hurt.  Both blades are referred to as the fang, or more lethal part of the knife.

Both blades?

Yes.  It’s a bent dagger.

The knife comes with an over-xeroxed booklet called the “Dirty Dozen and Then Some.”  The booklet shows you several self-defense techniques with the knife.  The normal grip for the Cobra is a saber grip and to bring the blades to play, you need some degree of hyper-extension. 

Be careful where you move your thumb to!

The Cobra, like almost all knives including the TDI and the QRT, can be held in a reverse grip.  In the reverse grip your wrist is in the neutral position.

Does the hyper-extension wash the Cobra out?  Nope, but it’s a consideration.  Another consideration is the fact that your thumb can slide onto the top blade if you extend it too far.  On the plus side the handle has sufficient distance from the blade to accommodate heavy winter gloves.  

The cobra doesn’t look like a knife in its sheath, a feature it shares with the TDI knife.  I find this to be valuable asset when I wear one in public.

I left the price blank.  If you shop around, you should be able to find a deal on any of these three.
 

My last impressions.

These knives target (if you pardon my expression) the police market.  The uniform and gun make police a target of opportunity.  Criminals know there is a gun present and exactly where it is.  Holding a bad person at gunpoint, an officer could be jumped by anyone from the guy's mother to his baby sister.  These same problems may apply to the armed civilian.  Having a fixed blade could make all the difference between regaining control and being found dead on the side of the road.

We throw a blanket statement of “It’s a tool, just a tool,” over any knife we carry.  I think you might find it difficult to explain to a jury what kind of tool the Cobra is.  It looks so wicked and excessively punishing you better have good reasons you can verbally and convincingly express.

I like the raw look to the QRT.  I think the blade needs a little polishing.  There’s a balance between so sharp it has a brittle edge and being robustly dull.  I think my QRT was a little too robustly dull. I polished the edge a little and I’m quite happy with its cutting ability.

The TDI knife is the standard by which all weapon retention tools are measured against.  It’s well made and has a refined elegance.  It doesn’t look menacing, doesn’t look dangerous and it’s likely it will not be noticed until it’s performing its designed function.  It’s my first choice, but I have sentimental reasons to like it.
