Boker vs Godzilla

I just got a new Boker Plus knife in to inspect.  Unfortunately for me, it’s for sale.  The Boker Urban Trapper is a great looking knife.  It’s very lightweight, partially due to its thin slender blade and partially due to its titanium and G-10 handle. 

The knife has a nice hand feel and good balance.  

The knife uses a small flipper to open and it depends on an IKBS ball-bearing pivot for its smoothness.  Not familiar with IKBS ball bearing designs?  Man, have you been hiding under a rock?

Here’s a link:  http://www.ikbsknifetech.com/11/1504.html

The design is so ingenious and so simple that most home hobbyists could make one.  Since they act like ball bearing races they let knives glide open.

So lets talk specifics:

Length open	7.75 inches
Blade length	3.5 inches
Blade thickness	0.1 inch
Steel	VG-10
Blade	Hollow ground clip point
Handle	G-10 over titanium
Handle thickness	0.4 inches
Weight	1.9 oz or the weight of a double rye whiskey, neat

VG-10 steel is one of the darling steels of the knife industry.  Originally marketed to Japanese chiefs, VG-10 was quickly adopted by the knife culture as a potential super steel.  It’s lived up to that promise. 

If you want to make some yourself, start with nice clean iron and add 1% carbon, 15% chromium, and 1% vanadium.  Add 1.5% cobalt and a pinch (just a 0.5%) manganese.  Mix well and allow to cool under precise conditions.  Ingredients are easy, cooling and heating are the key.  Just buy a Boker Urban Trapper.  It is already razor sharp!

The knife utilizes a frame lock to lock the blade open.  Titanium has wonderful properties, but excessive springiness isn’t one of them.  The G-10 scale limits the outward motion of the titanium frame lock.  It’s a clever solution to prevent over extension of the lock.

The removable, but sadly non-reversible, pocket clip also looks like titanium.  The knife is set up for right hand, tip-up carry.  The pocket clip provides for deep carry both to help retained the tool as well lower its visual profile.  I like to carry in my right side pocket, but drop this knife in any pocket and it will work well for you.

I don’t own this one, but I should.  This thin knife has a dressy business look that will work in the office, at urban play and more formal activities like funerals, weddings and board meetings.  It’s not the knife I’d pack away for elk hunting in Canada, but I’d carry it as a back-up when I was hunting.

It’s a good knife but VS Godzilla?  Well, it just my sense of humor, but several years ago there was a short cartoon video called Bambi VS Godzilla.  It showed Bambi standing alone when it was suddenly crushed by a giant lizard foot.  If Bambi had an Urban Trapper the cartoon might have ended differently.

Happy birthday Ka-Bar!

Nice sheaths!  Leather doesn't make any noise when it catches on a thorn or bramble bush.

It’s been pointed out to me that this is Ka-Bar’s 118th anniversary.  In a world where planned obsolescence is the goal, it’s hard to believe any company could last so long.

It was a Thursday, April 29 1897, in Pennsylvania, that a small company called Tidioute Cutlery came into existence.  That was the birth of Ka-Bar.  Several years later its assets were sold to start another company.

The buyer, Wallace R. Brown was the grandson of JR Case.  As with many of the traditional companies, Ka-Bar started with a different name and changed hands many times.  Starting as Union Razor Co., friction folders were made stamped with “Olcut” or “Keenwell” as well as “Ka-Bar”.

Almost all knife collectors have read or heard the story of the semi-illegible note received from some mountain man trapper who “kil a bar” with his knife.  The trademark KA-Bar soon became so famous and in such demand that the Union Cut Company changed their name to Ka-Bar.  During WWII, fighting knives were in demand.  With a little advice from the Marines and a little retooling, KA-Bar won a contract to make a general utility/fighting knife. 

Sargeant Dave E. Werner at Phu Bai.  Note the unstrapped Ka-Bar on left shoulder.  

The big beefy blade was attached to a rattail tang, which became the backbone of the stacked leather washer handle.  Even today, hunters of men and animals swear a leather washer handle works the best when your hands are covered in blood.

During WWII, I’m told, the knife had detractors claiming if you slapped the knife sideways you could snap the blade free of the rattail tang.  These detractors fail to mention we were also making ships that suddenly cracked for no apparent reason.  Metallurgy was just starting to make progress with metal processing and heat treatment and was still poorly understood.  They also don’t mention the relative short expected life span of the newbie in combat.  The cost accountants in the government were not about to give a $25 knife to man with a 12-minute life expectancy.  If you lived long enough you could always get a new knife off of someone who wasn’t a fast learner.  Today’s metallurgy turns 1095 carbon steel into a tool you can depend on when life is on the line. 

If the Buck 110 folder is the quintessential American locking folder, the Ka-Bar fighting/utility knife has fills that role for a fixed blade. 

You should own one.  One with a leather sheath, because it is quieter in the bush.

Aside:

Over 20 years ago Soldier of Fortune claimed you could safely conceal 12 inches of fighting knife in your waistband under a sport coat.  Might be time to start thinking about that again.  

Spyderco Spydercard

It's a funny looking knife, but it inspired the designers of other wallet hide-out knives.

I recently came across a Spydercard( C01).  They were very popular and people still collect them partially because of their scarcity, partially for the story associated with the knife designer.

First the knife. 

The Spydercard is the size of a credit card and 0.2 inch thick.  That’s about the thickness of 4 credit cards.  Designed to slip into your pocket or wallet, this 3.4 inch long knife opens to exposé a 2.4 in cutting edge.  The handle lock, like that used on the Square Head, secures the blade in the open position as well as the closed position. 

The AUS6 steel it is made from, was at the time, an entry level steel.  To keep costs down and provide reasonable performance, many knife manufacturers used AUS6.  This steel is comparable to 440A with a little extra kick.  The kick is vanadium.  This element forms tiny particles of vanadium carbide at the steel’s grain boundaries increasing hardness and edge retention.  The 14% chromium not only forms carbides but also forms an important transparent thin film of chromium oxide that protects the steel from oxidation or staining better known as rust.

Spydercard’s most popular blade configuration, as I remember it when I sold them, was the partially serrated.  On a small blade, especially with a hard-to-hold handle, increased cutting performance is critical.  This isn’t the sort of knife you pack for hiking the northwest Cascades, but you might pack it if you thought you might have to cut something to escape.

That's my wallet, a little over stuffed for my taste, but I could lose a few cards and squeeze that knife in.

The Designer

I wasn’t able to find much about the designer, Eduard Bradichansky.  He is described as a Russian Jew who immigrated to Israel, I assume, to escape the repressive Russian government.  He has been described as a gunsmith and jeweler who later worked with Spyderco designing what became known as the Spydercard and the Shabaria (C59).  He was apparently killed in a Hamas attack so brutal that identification was made based on dental records and the presence of Spydercard and Shabaria prototypes.  Sounds mysterious doesn’t it?

Well, I’m not going to ask Spyderco what really happened and wasn’t it just too convenient he had the prototypes on him.  I’m not into conspiracies.  I’ve always found that any conspiracy involving more than two people breaks down over time.

A little better look at the Spydercard's serrations

You know what they say, two can keep a secret especially if one of them is dead.

Poking the bear

The last knife gun show was a little slow at times, but I try to have fun with the prospective customers.  But sometimes things get out of hand…..

After inspecting every knife and asking such penetrating questions like what does Rockwell scale mean and what’s the name of the miner who dug the chromium, he started to walk off.

“Enjoy the museum show, sir.”  I said

He paused mid-step.  “Museum show?  Don’t you mean gun show.”  He had an amused look on his face.  Why not?  After all he just caught someone with a little mistake that might be amusing to him.

“No sir.  We’re the Lippincott Valley Satrap, largest recreationist group in the United States.  Once a year we put on our great show.”

“This isn’t a gun show?” 

“Thank you for the compliment sir.  We strive for perfect fidelity.”

“I don’t understand.  This isn’t a gun show?”

“This year we are recreating a gun show.  Last year we did a road rally that was so good, it took honors.  We’d like to do it a second time in a row." 

“So you’re telling me this stuff isn’t for sale.  Is that what trying to say.”

“No sir, I’m not trying.  I’m telling you, everything you see is owned by our members and part of their personal collections.  Nothing is for sale, well, almost nothing.”  I paused for a second and gave him my fingers-in-the-candy-bowl guilt look.  “A few guys have a small museum store.  You can buy stickers, pins and membership, but that s about it.”

“What about the guy over there selling raffle tickets?  Are you going tell me those are phony too.”

“No sir, those guys are real.  We always let NRA and Friends of the NRA set up and sell.  It adds a dimension of reality, doesn’t it?” 

He hadn’t fallen completely yet but I could tell he was having doubts, so I stopped talking and waited for him to step into it.

“What about the hawkers in the aisles holding guns?  I saw two men transfer money…”

“Part of the set up.  “It’s funny money we buy from a movie prop house.  Look, did you try to buy a gun from someone walking about?”

“Well, I talked to one guy, but he wouldn’t come down…”  I could see understanding was beginning to break through.

“That’s because he didn’t recognize you.  These guys set it up in advance with other members and everyone gets their stuff back, including the faux greenbacks.”

“I don’t believe you,” he said.  But I knew it was time to set the hook..

“Look buddy, I don’t care what you believe.  It’s no skin off my ass.  Go ask the ticket seller what kind of show this is.  But I got to tell you, if this is some kind of scam to get your money back, that’s not going to fly with them.  The club president assured me the sign outside the door would be clearly marked.”

I’d like to use that old Groucho Marx line about him leaving in a huff and a half, but he didn’t.  He just turned around and walked calmly and directly to the front of the show and the ticket window.  I’m not sure how that went.  I heard sirens shortly after he left my table.  I don’t know what happened, and I’m not going ask, either. 

It’s fun to go to the zoo, but you mustn’t tease animals too much.  You never know who’s really in the cage, do you?

Gifts

There are few gifts nicer than a pocketknife. 

If you don’t agree with that statement it is probable because no one ever gave you a pocket knife.  Recently I’ve been gifted with two.   Honestly, it’s impossible to determine if I like one more than the other.  It’s quite possible I like both of them equally.

My friend Tom sent me a nice Buck Slimline from customer appreciation days at Buck HQ.  As I understand it, many of the knives available at these days are of limited production and one and done uniqueness. 

Thanks Tom! 

The Buck Slimline is a nice one hand opening lock blade.  The steel is 420HC that has been cryogenically quenched.  Buck likes this steel a lot and with good reason.  It makes a great blade for general use.  420HC contains 0.45% carbon and 13% chromium.  The cryogenic heat treatment helps ensure the best combination of steel phases.  This all adds up to a stainless steel blade with a RHC of 58.  The blade is stain resistant and is hard enough to hold an edge, not be brittle and can be sharpened with ordinary stones. 

I love the black handle with blood red drizzle.  My love of Bucks started in college with the Buck 110.  I can’t tell you how many camp fires I’ve built with that Buck.  Now I have another, but it’s just too pretty to use!  I’m deeply touched by this Buck.

1996 Bullet Knife

My friend Paul passed on a number of years ago.  I met him because I was a shooting buddy of his wife and we grew close. Paul was a soft spoken man and I always found him to be dependable and keeper of his word.  These are virtues I value.  

I recently got his Remington 1996 bullet knife.  It’s in great shape, Paul seldom carried anything he thought was too fancy.  The knife has a master blade as well as a smaller blade.  It also comes with an awl, corkscrew, bottle opener/straight blade screwdriver and a nasty looking can opener. The blades are 440 stainless and the bolsters are nickel silver, a copper alloy containing copper, nickel and zinc, but despite its name, no silver.

The boxed knife lived in a drawer mostly because Paul, I suspect, was saving it for when he would really need it.  But I saw a very different connection.  The knife is called the Trailhand and Paul was a good man to ride the trail with.

P.S.  That is pretty tacky of you, Kevin, to post your price list as a comment on my blog without asking me.  If I had to guess, I would suspect you're friendless and will probably die alone and forgotten.  Make changes now while you still can.

Shadow Tech’s Claw

The large prototype folding Karambit

Originally, like so many martial art weapons, the karambit originated in southeast Asia. Inspired by the claws of big cats, the natives initially used this design for mundane activities, like raking roots, gathering threshing and planting rice.  Over time. circumstances forced the development of farm and every day implements into weapons of self-defense.

According to wikipedia:

“The karambit is held with the blade pointing downward from the bottom of the fist, usually curving forwards however occasionally backwards. While it is primarily used in a slashing or hooking motion, karambit with a finger ring are also used in a punching motion hitting the opponent with the finger ring. Some karambit are designed to be used in a hammering motion. This flexibility of striking methods is what makes it so useful in self-defense situations. The finger guard makes it difficult to disarm and allows the knife to be maneuvered in the fingers without losing one's grip.

The short Filipino karambit has found some favor in the West because such proponents allege the biomehanics of the weapon allow for more powerful cutting strokes and painful "ripping" wounds, and because its usability is hypothesized as more intuitive, though there continues to be debate about this matter.”

It takes hardly any effort to find self-promoting YouTube videos of how to use a fightin’ karambit.  Any of these complete videos can be purchased, …our operators are standing by…

The problem with fixed knives is they are not easy to conceal, a necessary condition of modern society.  Shadow Tech has been making fixed blade karambits for some time now.  They are currently, in a secret laboratory/dojo, developing two folding karambits.  And joking aside, they look pretty great.  I’ve only seen prototypes but they were very close to production models. 

Make that 2 to go, please.

I expect a there will be a little tweeking before and possible after release.  After all it is only mythology in which Venus springs forth from the ocean in all her perfection.  I do know the knives will be made from Crucible’s 154CM steel.  Some of the best knife companies use 154CM steel for their blades.  ST is using it for liners, liner lock and clips also.  The clip will be reversible and the knife rides tip up.  At least that was the plan when John and I talked about it.

Many knives, many fine knives have only a portion of the liner lock behind the blade

The liner lock will throw its complete thickness behind the blade spreading out the force of folding over a wide surface.  My limited experience suggests that may require a little more effort on your part to unlock the knife.  Pushing the liner lock over may require you to dig your thumb a little deeper in the lock, but you can image the painful consequences of having the lock fail.

ST tells me they will have two sizes, a large aggressive blade,

Large size

And a smaller blade. 

The small size

John tells me there will be several ways of snagging the blade’s opening stud and/or geometry to open the blade as you draw it from your pocket.  That’s very cool.  

Still remember what one veteran told me:

“I carry in my pocket.  If there could be trouble I move the knife from my pocket to behind my belt.  If I think there is going to be trouble, the unopened knife is carried in my hand.”

A karambit has the potential to increase even an unskilled person’s survival potential.  Give that and Shadow Tech some consideration.

Benchmade CLA

I just got my hands on Benchmade’s auto knife, the CLA.  I kept thinking the C stood for something military, or governmental-like, central or clandestine.  Instead it stands for the plebeian word, composite.  But don’t be fooled by that.  It may say Composite Lite Auto, but it’s a sweetie by any name.

The CLA is a relatively new addition to their black class of autos.

The heart of any knife is the steel.  The CLA has a 3.4 inch blade made of 154CM.  That’s Crucible Industries’ martensitic stainless steel.  Martensitic?  So much about steel can be laid at the feet of carbon.  If steel has a low enough level of carbon, the iron is arranged in patterns called ferrite, but it can’t hold very much carbon.  Hot iron can dissolve more carbon than cold, so as the metal cools out of the furnace, a form called austenite develops.  It can hold more carbon than ferrite, especial when hot.  Cool the hot austenite and it has to get rid of the excess carbon like a bad check.  Unfortunately by then everything is frozen solid, so austenite does the only thing possible: it changes shape to martensite.  This change in crystal system is what gives classic samurai swords their curved shapes, but that’s for another time.

The blade is tempered to 58-61 RHC.  Martensite can be made harder, but it also becomes brittle.  Brittle is the arch enemy of any blade.  Being a stainless the blade contains 14% chromium, which forms a transparent oxide film protecting it from all but the harshest conditions.  It’s called stain-less and not stain-proof for that reason.  The main difference between 154CM and 440C is the higher level of molybdenum.  Moly, as she’s known, also forms carbides like chromium.  These carbides help stabilize the crystals in the steel from deforming under pressure, which provides edge retention as well as strength.  The blades come as plain or partially serrated.  I normally prefer the plain edge based on looks, but the partial serration looks damn good too!

Enough about steel.  I never worry if knife companies like Benchmade, SOG or even Case are using the right steel.  They wouldn’t still be in business if they couldn’t get the best possible properties out of the metal.

Note the safety next to the large button.  The button is off set to add a layer of security.

The CLA’s handle is 4.45 inches long, under a half inch thick and curved to better fit your hand.  The scales are composed of G-10.  This material is a composite of woven glass cloth and epoxy resin cured under pressure.  It is very mechanically stable and resistant to most acids, solvents and bases as well as being an electrical insulator.  It’s entirely possible when cockroaches have replaced humans as the dominant species on earth, G-10 will still be hanging around.

Like all Benchmade autos the spring is stout enough to open the blade with authority.    Even a superficial examination of the knife shows the safety lock next to the release button.  I’ve always liked that.  You can off-safe it with your thumb and then simply roll on to the button to open the knife.  That’s nice!

The open box construction makes it easy to clean and oil.  Note the jimping at the back of the blade.

The pocket clip is left/right reversible and the knife is designed to be carried tip up.  The clip is placed to give you relatively deep pocket carry.  A hole next to the clip provides an attachment point for lanyards and retention devices.  It’s a nice knife and if I carried it over water or deep snow I’d use a retention line too!

The back of the blade has several lines of jimping which are carried onto the knife handle.  Jimping provides an additional friction surface as well as another tactile indicator of knife and blade orientation. 

I wish I could tell you how it cuts, but frankly it’s not necessary.  Benchmade knows how to sharpen an edge and how to correctly temper 145CM steel.  This knife is going to cut.  Besides, is slicing up a strip of cured horse hide really going to tell you how sharp it is?

I like the way the CLA feels in my hand.  I wouldn’t hesitate to carry this knife for everyday chores as well as off the beaten path contingencies.  If trouble comes looking, you might be very happy to have your own CLA!
