Excape!


Take a look at these.  Just ordinary pocket change, like you get from a thousand different purchases.  Or is it?

Penny for your thoughts?  Here's 48 cents worth of opinion.


Now take a look at this picture.  Same coins but something is significantly different. 

WTAF!

That’s right, the nickel has a blade.  It’s a very sharp blade.  It’s sold by Shomer-Tec.  I got mine from a good friend, Bob.

This is one of many products you’ll see aimed at people who travel in third world and failed countries.  In these locations kidnapping, abduction and murder are relatively common and quite anticipated.  FARC is a perfect example.  The great majority of their funding (even revolutionaries need to be paid) came from drug running and ransom kidnappings.  Having a hidden or non-detectable blade could be the difference between self-rescue and spending three years with an ear cut off while your family attempts to negotiate your release.

Think I’m blowing hot air up your skirt?  Check with your friends who travel to these countries for big companies.  They have hostage insurance and training for the traveler to look less like a target as well as special security.  Tell me again why you think you’re safe at Cozumel?

You don’t really use this blade.  It’s designed to help free yourself from cord or zip-tie imprisonment or as a last ditch effort to escape during the initial stage of an abduction or assault.

coin knife
1986 was a very very rough year as witness the coins.

It does remind me of the devices invented by OSS and others to help Allied prisoners-of-war to escape.  I have a plastic copy of a lapel knife worn in a sheath sewn in jacket lapels or in coat sleeves.  The originals were metal and quite deadly.

Growing up in the 50s there were a lot of articles about these efforts.  I remember jacket buttons that would unscrew to reveal a simple compass.  When the Nazis caught on they made them with reverse threads so it was righty loosie, lefty tighty.  Uniforms were redesigned so simple alteration would make them resemble men’s suits and ballpoint pens containing an ink that would dye a re-tailored uniform to typical suit color.

I think you could drop this in the change bowl at any metal detector and it would pass.  You have to notice the dot between In and God 

Escape tools aren’t anything new.  Still, this is a very cool knife.

Two-Way with Benchmade


In this corner we have Benchmade’s Anthem and in the opposite corner we have Benchmade’s Bugout.  All right, I want a clean fight.  No clip gouging, no biting and no hitting below the axis lock.  Okay?  Now go to your corners and come out on the bell.

Bonggggg!

This is an unfair fight.  But let’s see how it shakes out.

The Anthem is a manual opener with Benchmade’s famous AXIS lock.  Introduced in 2017, its unique feature is the handle is machined out of a solid billet of titanium.  For the same strength, titanium is 45% lighter than steel.  So this knife weighs in at 3.66 ounces.  The titanium handle is sculpted in a chevron pattern that is pleasing to the touch and attractive to the eye.  The knife is set up for tip up carry and the titanium clip is left/right reversible.

Hey, good looking...

As soon as anyone uses the term wonder steel, a new one appears on the horizon.  Still it is the correct adjective to describe this steel.  Let’s talk composition.

20CV is a martensitic steel containing 1.9% carbon, 20% chromium and a whopping 4% vanadium with 1% molybdenum and a smidge of tungsten.  The high concentration of carbon and vanadium produces a high volume of incredibly hard vanadium carbides.  These carbides strengthen the steel and give it wear resistance which benefits any knife blade.  The chrome rich steel has excellent corrosion resistance. 

Starting as a powder steel 20CV has small grain and uniform distribution of tiny carbide grains.  But machining is difficult, having only 35-40 percent of the machinability of 1% carbon steel.  Hardening, annealing, tempering operations are complex and time consuming.  Despite these complications the Anthem’s blade reaches 59-61HRC.

The opening stud is easy to find and is spaced nicely from the body allowing easy access.  The blade glides open on what looks like bronze washers.

It’s a beautiful knife.

If I had to summarize Benchmade’s Bugout, I would have to say: “Now for something completely different!”  I also have to add different isn’t bad.

The Bugout was introduced this year, 2018.  It too is a manual opener with an AXIS lock.  It’s thinner, lighter and more compact than the Anthem.  The steel is CPM S30V, another super steel.

S30V is a martensitic steel containing 1.4% carbon, 14% chromium and also 4% vanadium with 2% molybdenum. The rest of course is iron.  Vanadium reacts with carbon to produce very hard carbides.  Harder than chromium carbide.  Generally, steel has to contain 10.5 % chromium to be considered stainless.  One factor to consider in this equation is how much of the chromium is removed from the metal as carbides.  Fortunately, as chemical reactions go, vanadium carbides are the favored product, so most of the chromium is available for protection from oxidation or staining.

A nice Introduction to Benchmade quality knives.

Powdered metal products, in general, have smaller grain size and a better distribution of the carbides than cast steel.  It’s reported to be as easy as D2 steel to machine, which according the fount of all knowledge, Wikipedia, isn’t all that easy. 

Hardening, annealing, tempering operations seem to be relatively straight forward.  Bugout’s blade reaches 58-60HRC.

The handle is a glass fiber filler nylon called Grivory.  It one of many types of engineering nylons and its properties are well understood.  There will not be any surprises here.

The knife is set up for tip up and the metal clip is reversible left/right and set up for deep pocket carry.

Partial Steel Liners Bugout
You can see the steel liner ending just at the top finger.  there's a second one on the other side.

The knife doesn’t have full handle metal liners.  The metal liner is about 1.7 inches long and it looks like it’s injection molded into the handle and then screwed at the tail end for additional strength.  The opening stud has a nice blue color but it’s held near to the grip making the knife a little more difficult to open as compared to the Anthem.  The AXIS lock is also tucked into the handle and the blade doesn’t swing free when the AXIS lock is used as does the Anthem.

CATRA edge testing is one of the new witchcraft testing procedures to produce a reproducible, operator independent, meaningful edge retention value.  The problem with many of these types of test is finding a test material that is also constant and reproducible.  In any case it’s better than you and buddy shaving leather or cutting steaks.

So, what do I think?
These are knives designed for different needs and different people. 

The Bugout is a nice “Welcome to Benchmade” knife.  It’s small and compact but provides enough cutting ability for most uses.  It’s the knife I would carry in places I couldn’t carry a knife.  Places I thought I might lose a knife.  If I was packing a true hell-for–leather bugout bag, one of the knives would be a Bugout.  If I was going to stash a knife, a couple hundred in twenties, compass and matches in a sealed wax container… you get the idea.

The Anthem, well, it a great knife and for me it would a “barbecue” knife.  Something I’d pull out of my pocket to show off.  I’d carry it in places where I never intended to use a knife.  It would be a status symbol for me, if I used those kinds of status symbols.  But look, if you need to get the most out of a knife, if you use a blade hard and need every possible advantage of edge, weight and durability, the Anthem could be your answer.  It’s pricey, but I think it would hold up better than the Bugout to hard, brutal use.
