Launch 13

I just got my hands on Kershaw’s Launch 13.  It’s a very icey knife.  But then, I’ve always liked Kershaw knives.

Kershaw Launch 13

Pete Kershaw started the company in 1979 when he left Gerber Blades.  At the time, Ichiro Hattori made most of Kershaw’s knives in Japan.  Constantly evolving, Kershaw has introduced many innovative knives designed by people like Ken Onion, Ernest Emerson, Frank Centofante, and Rick Hinderer, to name a few.

The internet claims Kershaw makes over a million knives a year.  Impressive.

Pete retired from Kershaw on June 1, 1998, and by that time, Kershaw was connected with KAI and is now wholly owned by the KAI Group. 

I really like the blade and dark green handle.  CMP 154 is a nice knife steel.

The Launch series was introduced in the 2015 catalog with the Launch 1, 2, and 3 knives.  It was a bold move.  It was at a time when many states still had restrictions on automatic knives.  More of these interesting automatic knives were released over the years, constantly exciting knife fanciers.  In 2019, the Launch 13 Auto was released.

Here are some Launch 13 stats:

The blade is made from CPM 154 powdered metal and hardened to HRc of 58-60.  This is hard enough to retain an edge and not be brittle. The blade is a little over 0.1 inches thick and has a tapered false edge, giving the blade a jazzy look.

If a knife doesn't feel good in your hand, it's the wrong knife for you.  This one feels great!

Crucible 154CM is a martensitic stainless steel similar to type 440C but fortified with molybdenum.  Like many knife steels, it was initially developed for challenging industrial applications.  Those properties made it a desirable material for knife makers.  

The blade is a high saber grind Wharncliffe mounted in a strikingly attractive sculpted aluminum handle.  The low-profile button helps prevent accidental opening, and the deep carry pocket clip is reversible. 

The knife arrived set up for right-hand and tip-up carry, which is perfect, as I carry folding blades against the back edge of my pant's right pocket.

The knife weighs in at 2.4 oz.  Surprisingly, the balance point puts the weight chiefly on the handle.  I like this as it makes the blade feel lively.

The clip can be reversed for left or right pocket carry

This one is a special edition in a dark olive green that I find attractive.  The Launch 13 has been out for a while, but this is the first dark green one I’ve seen.

SMOCK!

 

“Hey, you got my knife!”

That's different from what I hear very often at my sales table.  Often, I hear, "You got the knife I’m looking for!’ or the slightly different version, ‘You got the knife I lost!’  Neither of these states assures you of a sale.

“You’re Mr. Smock?” I ask.  He was pointing at Spyderco’s Smock in carbon fiber.

You must understand I grew up with Steve Allen's late-night TV show, Tonight.   Allan launched the careers of people like Don Knotts, Lewis Nye, Bill Dana, and many more.  But it was his catch phrase that always fascinated me:  'Smock, Smock."

So, when Mr. Smock walked up to my table and introduced himself, I was, without a doubt, at a loss for words and very confused.

Kevin Smock 
He's holding a flier for the WRCA Knife show in April 6 and 7th at MAPS

                                                           near the Akron-Canton Airport

“Yes, I am, and you," he said, pointing at the Smock on my table, "have the new pivot.  I didn’t like the old one.”  It turns out he is Kevin Smock, the designer of Spyderco’s Smock.  The previous one was a simple screw head inset in the carbon fiber handle.  The new one is a polished metal head with an aerospace look. 

I like the look, that button release is totally icey

I've met other famous knife designers, but usually at the SHOT Show or Blade.  But never at the Medina Community Center until today. 

Kevin started as a knife modifier.  He would take other factory knives and modify them, creating unique, one-of-a-kind knives.  This is a bigger knife hobby than you might think.  Facebook is filled with postings of 'patina-ized’ blades, replaced grips, and altered grinds.  I met a fellow who shortened the blades and sometimes the grip of factory knives.  Finally, Kevin’s friends told him, ‘Look, you got the skill and the knowledge; you should be making your own knives.'

That did it.  Kevin wanted to use Spyderco's top compression lock, so he approached them and got permission.  The result is the SK23.

 

Notice the flipper, it's very easy to use and doesn't distract from the streamline profile.  

Later, Kevin showed Eric Glesser his creation and Eric was impressed.  He gave Kevin his card and told him we should talk.  The rest is history.

You can look up Spyderco’s Smock for yourself.  It’s a very cool knife.  The flipper is uniquely positioned and utilizes a button to disengage the compression lock.  The button lets you close the knife without your fingers coming near the closing blade.  That’s a nice touch.

If you don’t think this is significant, you’re wrong.  I constantly deal with people who want a knife, in some cases need a knife, but worry about cutting themselves while closing the knife.  A lot of effort and time goes into finding a knife they feel comfortable with.  This apprehension is especially common with frame and liner locks.

The Smock weighs in at 3.7 oz, and the blade, incompletely described as a modified Wharncliffe, is ground from CPMS30V steel. 

Kevin still makes his SK23 but also makes custom scales for the Spyderco Smock.  You can check out these and other items at https://www.smockknives.com/

Meeting him made my day.  Here's an entrepreneur creating industry and generating profits.  There's a lot to be said for that.

Two to Show

As luck would have it, I had a chance to pick up two new knives. 

The first is the OSS Dagger by WE K’nife.  I've always been interested in the small ‘James Bond secret agent’ knives.   I have heard about a replicate kit of special knives made for the OSS, but I have never seen one.  Perhaps it is just urban legend.  In any case, a small concealable dagger would be part of that kit.

Whenever I think of the OSS, I remember "You're Stepping on My Cloak and Dagger" by Roger Hall

The WE OSS dagger is a tribute to those days.  The knife is made from CPM 20CV steel.  CPM20CV is considered one of the super steels with amazing edge retention.  The formula is 1.9% carbon, 20% chromium, 4% vanadium, 1% molybdenum, and 0.6% tungsten.  But this only tells part of the story.  Heat treatment and edge geometry can make or break any steel.  In this case, vanadium and chromium help create fine-grain carbides and allow for sufficient chromium for stain resistance.  The downside is that 20CV can be extremely challenging to properly sharpen.

A lot of bulky Kydex for a secret concealed tool

The OSS Dagger has a flat back, making the knife less than 1/8 inch thick.  This allows the knife to sit snuggly in tight places.  The two-inch blade is sharpened on both sides, as fitting a dagger.  The flat grind slopes upward to a groove in the knife's spine.  The edges flow to a thin, sharp point. 

Face it, it's a weapon

A depression for the thumb has ridges of G10 to improve grip.  There isn’t a guard on this knife.  I have to remind myself this is a soft target weapon.  The handle has a lanyard hole, and if it is in use, I'd suggest a short lanyard.  The cord, or leather ribbon, can then be threaded between your fingers for additional grip.  A flexible cord could aid you in drawing the knife, depending on your hiding place.

The OSS Dagger comes with a Kydex sheath.  The sheath has a very nice spring-loaded clip to secure your weapon.  It is removable, and WE provides a ball chain to convert it to a neck knife.  You could also sew the sheath in to a pocket or jacket sleeve.  The knife weighs less than ¾ of an ounce.  The sheath, unfortunately, weighs more.

Let's stop kidding each other.  This isn't wartime.  This knife isn’t being issued to people dropping behind enemy lines.  It’s just a paean to one specific tool used by the OSS during WWII.

But I’d find some thinner Kydex and make a smaller, lighter sheath if I needed this last-resort weapon.

Olight is best known for their flash and weapon lights.  They are a relatively new company, founded in China in 2007.  They are not without their fans and critics, with some justification.  In November 2017, a man was killed by an Olight flashlight that exploded due to improper use after placing it in his mouth.  Late in March 2022, Olight recalled 215,000 flashlights because of a defect that caused the lights to accidentally turn on and sometimes burn the owners.

Not my first zombie knife
https://knifesearch.blogspot.com/2023/12/zombies.html 

Despite this, I snatched up one of their Nettle 2 Zombie knives.  The blood-splattered (really, just red coloration) green handle speaks to me.

The 2.8-inch blackened blade is a high-shoulder flat grind.  It is fashioned from  154CM  steel.  Crucible Industries 154CM is a modification of 440C, a martensitic-type stainless steel to which molybdenum has been added to improve its physical properties.  However, this is not the powder metal form. 

The challenge coin was a suprise!

The handle is an aluminum alloy, which lets the knife weigh in at 2.5 ounces.  The handle is set up with a reversible clip and comes out of the box, right-hand tip-up, my favorite way of carrying a knife.

The knife has a button lock, which allows two ways of opening the knife, actually three.  The first is the blade flipper, which rotates to become part of a finger guard when the blade locks open.  The second is using the lock button and allowing gravity to open the blade.  You can also flick your wrist if you want that tactical click.  The last way is using the tiny opening depression in the blade to pinch the blade open.  That’s the polite society way; it doesn't alarm anyone.  Ask me how I discovered the need to open a knife this way, and I'll tell you about a pizza party at work.

Mettle 2 Zombie

 

I don't think I'll be carrying either knife.  Both knives will become part of my collection.

 

Magnificent MagnaCut

 

Crucible Powdered Metal’s MagnaCut steel is, perhaps the best performance steel on the market.  It is certainly the hottest!

Dr. Larrin Thomas, its inventor, thought there should be a steel that could be optimized to give small grain steel with tiny, supper hard carbides capable of reaching Rockwell 60+ hardness without brittleness and still be rust resistant.

I’ve taken a very short step in to metallurgy and perhaps the first thing you learn is you simply can’t throw elements into a pot and get a great outcome.  Metallurgy is complicated, heat treatment is a specialty, and you just don’t plunge a red-hot knife from the forge into oil and get a great outcome.

MagnaCut was the result of serious study and testing which culminated with a single hit or miss lot of steel.  Larrin got one bite at the apple and he was successful.  The story of its development is here: https://knifesteelnerds.com/2021/03/25/cpm-magnacut

One of Spyderco's MagnaCut folders: 

Let me be honest with you.  The article is written for steel nerds, people who enjoy technical data, like hard science fiction and enjoy reading about science.  I’m one of them.

The upshot is MagnaCut, due to its properties, when processed properly is an amazing steel.  The high-end knife makers jumped on it like white on rice.  This quickly worked its way down to EDC knives.

You can Google MagnaCut and any knife company and get a hit.

Here’s the formulation: Carbon 1.15%, Chromium 10.7%, Vanadium 4.00%, Molybdenum 2.00%, Niobium 2.00%, Nitrogen 0.20%.

Kershaw Launch 4 in MagnaCut

The amazing thing, all the chromium is available for corrosion resistance.  The  carbides are all vanadium and niobium.

We could talk about Charpy C-notch test, Edge Retention (CATRA Testing Relative to 440C), salt spray corrosion test, but you can find that yourself.  The important thing is to realize this steel helps makers use a better blade geometry for improved cutting while ensuring extended performance.  And while performance doesn’t come cheap, this steel is worth it!

Bestech's Swordfish in Magnacut

You’re going to see a lot of MagnaCut in the future.

Zombies

Zombies weren’t always so threatening.

It took a lot of work and juju to turn a person into a Zombie.  They mostly stood around until the Zombie master gave them commands.  Even then, they were primarily insistent; nothing stopped them from carrying out their instructions.  And they weren’t infectious.

In Piers Anthony's 'Castle Roogna', they were pretty nice people, had a lot of friends, fell in love, and did other ordinary things. 

The first record of zombies in literature goes to the English poet Robert Southey in 1819.  Later, Richard Matheson published  'I Am Legend' in 1954.  Sparked by that idea, George Romero directed 'Night of the Living Dead' in 1968, and zombies became insatiable, highly infectious, deadly creatures driven by a killing desire for brains.

Most of the TV shows and movies copied this idea.  It seems there is limited originality in the entertainment media.

We saw a shift in 2005.  Inspired by an old folk legend, Tim Burton produced ‘The Corpse Bride,' suitable for children and adults.  Later in 2019, 'iZombie', a comedy crime drama TV show, ran for several seasons.

MicroTech's ZombiTech

I'm not a Zombie fan, but I fell hard for Microtech's ZombieTech out-the-front auto.

Something about the blood splatter.  I've always been interested in blood splatter, and the almost florescent green handle appeals to me.

The classic way to stop a zombie was to destroy the brain

MicroTech released the ZombieTech in 2012.  I have one from 2019 celebrating Microtech’s 25th anniversary, but I don’t know how much longer they were in production.

I contacted MicroTech, but they remain closed-lipped about everything and have yet to respond.

Real blood doesn't splatter this way, unless it's a high speed splatter

The internet claims that every ZombieTech has a random and different splatter pattern.  I admit that some patterns are a lot nicer than others. 

The 3-inch blade was available as a drop point, tanto, and a double-edge dagger.  I have found images of bright blades and ones with a black finish.  While some websites claim to have a few high-end ZombieTech sets in stock, most say 'Out of  Stock,' which is seller speak for can't get it anymore.

MicroTech uses M390 steel from Böhler Edelstahl GmbH & Co KG factory in Kapfenberg, Austria.  Originally designed in the late 1980s for molds used in the injection molding industry, it has found a home in the knife community.

I like OTFs, or Out the Front, but they have their limitations too.  Blade can slip off the internal carriage.

I really shouldn’t bang on the entertainment industry too hard.  Originality is hard to come by.  In 2021, MicroTech released a version of their knife called 'Outbreak.'  https://microtechknives.com/the-outbreak-unleashing/  It sports the same blood splatter on bulbous green and a Biohazard symbol.  It, too, is out of stock.

Screw Loose

 My wife’s current favorite pocketknife, a purple SixLeaf, lost the screw holding the clip to the body.  Fortunately, the knife slipped further into her pocket, and somehow, the clip was retained.  The screw, however, vanished.

Of course, I wanted to repair it.  SixLeafs aren’t that expensive and but there are no local distributors I can contact for a replacement screw. 

Fortunately, I had a SixLeaf of my own and was able to confirm it was the same screw.  But what kind of screw?

She wanted the purple one and I opted for green

My friend Derrick speaks fluent machinist.  He was able to identify it as 2.5mm X .45 screw.  In the bonus round, he even produced the proper replacement screw.

We had the knife and the clip and when we got the screw, well, everything worked.

That greatly simplified my job.  I didn’t want to force an incorrect thread into the knife's titanium frame, so having the correct one was excellent. 

Lot of brands available, any one would work

I got out my semi-permanent (blue) threadlock and #9 Torx drivers and went to work.  I used a single drop and let the threadlocker wet the threads and drained off the excess into a paper towel.  This left me with a tiny ribbon of blue winding around the thread root.  I screwed everything back together, finger-tight.

Done!

My wife got her favorite knife back, so it’s a great outcome in my book.

Thanks, Derrick!

What's In Your Stocking?

Stocking stuffers?  We don’t need no stinkin’ stocking stuffers…

That's not true, is it?  During the Christmas Holidays, there is always a need for little gifts.  This is especially true if you're a knife fancier.  We all need oils, waxes, polishes, sharpening doodads, and whatnots, but we sometimes hesitate to buy for ourselves.

Let me give you two ideas any knife fancier will want.

There are various products like these two, I just happen to have these on hand.

Every pocket knife I’ve owned has screws, nuts, and bolts that all what to back out and get lost.  Every clip has at least one screw that wants to be somewhere else.

The solution: Threadlock.  People have used nail polish, airplane glue, paint, and other solutions to keep screws from backing out.  McBride writes during the Great War, WWI, he and other shooters rusted their screws in place with iodine.  There are better solutions for a pocket knife.

I'd get the blue semi-permanent.  It will keep the gremlins from backing out screws.

The trend today is to use torx screws.  Those are the screws that need a star-shaped driver.  They are the hot fasteners today, and most of your knives will be assembled with these specialty screws.  If you want to replace a clip, disassemble, and clean your knife, you’ll need the correct torx driver.  Husky makes a nice set of four double-ended drives housed in a nice plastic body.  The end cap rotates so you can put finger pressure on it and still turn the driver.  The drives range from the tiny T4 to the smallish T15.

Two easy stocking stuffers for your favorite knife owner, even if you buy these for yourself.

Secrets of the Sorting Hat

 

I've moved, which forced me to confront my knife collection with the certainty that all good things end.  My previous dwelling had plentiful storage, but the new digs, well, not so much.  I’ll add cabinets, shelves, and drawers for storage, but I need to deal with limited storage and the need to put things away.

The move has also prompted a confrontation with my mortality.  Do I want to continue to curate knives I have for no apparent reason?  As much as I wish it, I do not have a Harry Potter sorting hat to make determinations for me.

I realized that all my possessions could be categorized into two distinct classes and a third, more nebulous one.  The first two are obviously "Keep" and "Discard.”  The third is “Maybe.”

Don't let this fool you.  There are only two options.  Maybe is actually a Discard.  If a knife doesn't create enough passion to become a Keep instantly, it's a Discard you're trying to be polite to.  Ditch it.

The original Tigersharp

Here’s a couple of examples.  I picked up a Tigersharp at the SHOT Show.  The company later sold the design to Camillus.  The novelty is the replacement blade eliminating the need to resharpen the knife; just use a new blade.  It's going.

Boot dagger from S&W

Years ago, at the Knob Creek Machine Gun Shoot, I bought a S&W H.R.T. dagger boot knife.  I am still trying to understand why.  The handle is too small, the blade is sharp on one side but not the other, and I don't typically wear the proper boots.  Bye-bye boot knife.

Boker's Pocket Knife by Mickey Yurco

I bought a knife from Boker, designed by Mickey Yurco, called the Pocket Knife.  Mickey told me he thinks of it as a self-defense tool, but Boker, fearful of public backlash (What!  You mean to tell me you could hurt someone with a knife?) calls it a camping or survival knife.  I wore this on my pack for years.  It's a keeper.

So, there you have it.  When you start thinking about that great collector's meeting in the sky and can't decide what knives need to find a new home, remember, Maybes are just polite Discards.  You really didn't care for them in the first place.

 

Unpack: CRKT's Kith and Razelcliffe

 

Receiving and unpacking knives is one of my favorite activities.

I just got two from Columbia River Knife and Tool and they are both winners.  The first knife is the Razelcliffe, designed by Jon Graham and the other, the Kith, designed by Ken Steigerwalt.

The top is the Razelcliffe and the bottom the Kith.

The Kith is a locking folder with a 3-inch blade ground from 8CR13MoV stainless steel.  It is a good knife steel, especially for a working knife.  Compared to D2 (you'll see why later), D2 tends to have more edge retention and hardness than 8Cr13MoV but is more expensive and less corrosion resistant.

The Kith utilizes a front lock set in the 3.75-inch glass-reinforced nylon handle.  It is relatively lightweight at 2.3 ounces; I get mail heavier than that.  I like the handle, but the contrast in the black handle is not from pigmentation but surface geometry. 

Unfortunately, the gray handle spots are just different reflectivity

It's a good length for many basic jobs at a campsite, fishing, in the office, or preparing the yard for winter.  The Kith has an MSRP of $40.  You can't go wrong at that price for a working knife.

 

Years ago, I had a Razel with a stag handle from CRKT.  I last saw it in the pocket of an Australian heading home to their anti-knife culture.  I hope he made it.  It was a very cool knife.

The Razelcliffe, let me suggest it would make a very icey club knife.

The Razelcliffe is also very cool.  The 2-inch blade is made from D-2 steel (see, I said we'd get back here).  D2 isn't quite stainless, but I never see rust on any D2 knives I own.  A little oil takes care of all my problems.  D2 takes and holds a good edge and can be resharpened with basic stones.  The Razelcliffe utilizes a frame lock and IKBS ball-bearing pivot.  That is very cool!

The G-10 handle is 3.25 inches long, and the knife weighs 3.3 ounces. 

The MSRP is $48, a reasonable price for a step up in cool factors. 

I've always thought CRKT over-engineers their knives.  You get a lot of knife for a reasonable price.  That’s invaluable in a world where you pay for a name.

 

The Future of Knife Making

 This could be the future of knife making.

These beads are the results of 3D printing

Yes, really.

These beads are 3-D printed plastic and can be any color, texture or shape you want by Chroma Scales.  You could customize any sort of knife scales/handle you want.  This is the beginning of the future.

Several years ago I saw a demonstration of 3-D metal printing.  Essentially it was a computer-controlled arc welding system that would deposit a spot of metal and build up a 3-D component.  This has evolved into printing metal engineering components and prototypes using high purity metals and laser beams.  Lincoln Electric is using this technology as is 6K Inc.  Many companies now offer this service.

 Miniaturization is a economical driving factor.  Big things will get smaller and find a way into your home.  Look at computers and microwave ovens 

One video showed a company printing out manifolds out of 316L, a low carbon stainless steel.  Not the best for knife blades, I grant you.  They video demoed a Trumpf TruPrint 3000.

Prices are still high, but you can buy 3-D printers that use plastic on Amazon now at reasonable prices, from under $200 to around $3000.  The polymer used is very affordable.

I was able to find glass fiber reinforced polymer, which gives the finished product high strength.  I believe carbon black reinforced polymer is available.  High strength metal alloys are just a bit farther down the road.

We’ll see the big guys, like Spyderco, Benchmade, Civivi, or Buck use it first to print unique blade shapes and designs.  But what about temper and hardness?  How will they heat treat it and such?  I remember those same questions asked about powdered metal.  Early adopters had problems with porosity, just ask Kimber.  They found answers.

The big change will occur then you no longer buy a knife, but purchase a program to print your own.  I suspect there will be acceptable options built into the software which will come with a license for one or more printings at which point it erases itself.  Code hackers will find a way to tweek the code to make unique knives or print unlicensed copies.  We see that problem with knockoffs.

There will be laws forbidding this and a new class of criminals. 

Remember the Star Trek episode ‘Tomorrow is Yesterday’?  A plot complication  occurs when the ship beams up an Air Forse security officer from the 1960s.  They keep him in the transporter room as to minimize the historic contamination from the future.  Scotty tries to relax him by offering the fellow Scotsman a dish of haggis from the replicator.  What is a replicator but a fast 3D printer?

You’ve seen the future.

Get Your Knife!

We are coming up on National Knife Day.  Yes, there is a national day commemorating the knife. 

 We sometime forget how important knives are to the story of civilization, perhaps to the evolution of humanity.  I often think early man’s first tool was a stick to extend his reach, followed by a rock to pound things.  Somewhere along the way he got the idea of cutting things and everything took off!

We have been celebrating National Knife Day since 2011.  For some of us, every day is a celebration of knives.  Knives fill our lives both in the physical sense and in our thought process.  Our cars have windshield wiper blades, I buttered my toast with a knife, the mill at work has a doctor blade, we need something to slit the envelope open to announce the winner.  And nobody tried to cut the cake without a knife.

 

We cut to the bottom line, a foolish person is described as “not the sharpest knife in the drawer.”  We like (sometimes) people with a razor wit, we cut the fat out of a job quote, and we want to sharpen the pencil to work a better deal.  

 

Rumor has it the day was selected from a letter written August 24, 1838, by Rezin Bowie, claiming he (and not his brother, Jim) was the actual creator of the Bowie Knife and deserved the fame and credit for it.  Of course, Jim was dead by then…

 

Celebrate August 24 by carrying your favorite knife.  Maybe show it a little respect by sharpening the edge and wiping it down.  A drop of oil isn’t too extravagant, is it?

Remember the proverb:  “A knife-less man (and woman) is a lifeless man.”

SixLeaf Knives

 My friend Derrick introduced me to SixLeaf Knives.  After handling and opening the knife, the question, "Where did you buy that cutie?" was not politeness.  I really wanted one.

Actually, I ended up buying three!

He found it on eBay.  You have to win your auction, and SixLeaf will ship you one from Yangjiang, China.  Yangjiang, I am told, is moderately famous for making knives, scissors, swords — anything that cuts.

I won my auction, and despite the warning of how long it could take (46 business days!), it arrived in a couple weeks.  I liked it so much that I bid and won a second one.  It arrived just as quickly.

Prices can vary because you're bidding against someone who thinks they want it more than you. 

Let’s take a look at it.  The matte blade is 3.25 inches long and 0.125 inches thick at the spine.  The blade is a drop point with, for all practical purposes, a flat grind.  The steel is D2, hardened to Rockwell C 60.

Good looking knives.

I like D2 steel.  It is seeing a resurgence in the knife world.  It’s almost stainless, so it takes a little care to prevent rust formation.

The 4-inch handle is titanium with linen Micarta scales.  This keeps the weight of the knife under 2.9 ounces.  The lock mechanism is a frame lock, and to compensate for titanium's softness, a small steel insert makes contact with the back of the steel blade.

The knife is designed to open with a flipper, and the blade flies open on KVT ceramic ball bearings.  These are used by companies like ZT and others. 

A 3.25 inch blade is, for most parts, a perfect size for EDC.

Is it perfect?

No.  The clip isn't reversible.  The knife arrives set up for right-hand, tip-up carry.  That's my preferred carry mode, but it is not a universal standard. 

Closed, there is a little height difference where the frame lock meets the frame.  Just enough of a difference you can feel it when you rub your thumb over it. 

The frame lock engages very nice, with quite a bit of contact with back of the blade

And if I’m picky enough, I would point out that when open, the frame lock separates slightly from the Micarta scales.

I like the linen Micarta scales.  They look and feel nice.

Frankly, for an under $50 knife (It's an auction.  Your price may differ.) you can't beat a SixLeaf.  I like them so much, I gave my wife one!
