Swiza


Move over Swiss Army knives!  You’re got company.


Swiza is a relatively new knife company, but they have a long history as a clock maker.  Louis Schwab established the Swiza clock factory in Moutier, Switzerland where they have a long reputation as a premiere clock and watch maker.  But change comes to everyone. 

In 2006, the Schwab family transferred ownership to Bedonna Holdings.  Who are they?  Good question.  Bedonna appears to be a holding company whose business is making money.  Like all holding companies, they own several companies that make products the public wants.  Kind of like angels on “Shark Tank.”

At some point Swiza got involved with estragon, a design company.  Yes, it’s a lower case “E,” all very artsy fartsy.  But Dirk Fleischhut and André Lüthy appear to have the chops.  They helped Swiza get into the knife game with a very interesting knife.

They opened a plant in Jura, Switzerland, and in Oct 2015 started making Swiza knives, a creditable challenger to the Victorinox/Wenger Empire.


Here’s a little aside I found interesting: the geology term "Jurassic" is derived from the Jura Alps, which date to that era.  Knives and fossils in the same blog, must be a record of some kind.

Here’s a Swiza D06 in leafy green.  Let’s talk turkey, err… rather knife. 

The first thing you notice is the nail nicks or blade openers.  They are elongated trapezoids holes that penetrate the blade or tool.   The second thing you notice waits for you to pick it up.  The bolsters have a soft silky feel.  Rub your thumb over the closed knife.  There aren’t any sharp edges with the exception of the back end of the tweezers.  You’ll find a curious double step that lets you grab and remove the tweezers very easily.

The 3 inch blade is milled from 440C stainless steel and has a Rockwell “C” hardness of 57.  The blade locks open, a touch I have always liked.  The release is hidden under the white Swiss cross on the handle.  It takes a little effort, but that’s actually desirable in a locking knife.


Various tool configurations are available.  This knife has in addition to the tweezers and main blade, a #1 Philips screwdriver, a #1 and #3 flathead, bottle opener, can opener and a reamer with sewing awl eye.  I’ve always been curious about the sewing awl eye.  If you’re using that function, that’s going to be a very coarse repair which will probably do more damage than the rip, or the fabric is so coarse you can wiggle it through without cutting large holes.

I seldom need a can opener, but the screw drivers and bottle opener are life savers!


The tools appear to have been hardened to 54HRc.  Why such relatively low hardness, you ask?

It’s not low.  We’re spoiled by pricey super steels with Rockwell values in the 60s.  At these levels bending the blade is likely to break the blade.  As Ernie Emerson once wrote, a bent blade is still a knife, a broken blade is just expensive junk.  (My apologies if the quote is wrong.)

At these levels of hardness you should be able to resharpen the edge with a fine grain rock.  A number of years ago, I attended a mini-class where it was claimed you could sharpen a blade with mud. That is, if you had enough time, and if the knife was dull enough that even a slight improvement was desirable.  I’d look for a fine grain, flat rock first.

All in all, I think you’ll find the Swiza up to all your urban cutting needs.  This Swiza, with its leafy green scales has a suggested manufacturing price of around $56.

Puukko


"A knifeless man is a lifeless man.”  Nordic proverb.

I recently bought a set of puukko knives.  The set has the curious name of Double Big Hunting (Knives) and was designed by Harri Merimaa.  Harri is from Bothnia, a providence of western Finland and is a third generation knife maker.  I think they are very nice knives and I'm very happy to have them.  Nice job, Harri!

The blades are high carbon steel, the smaller knife is 84 mm (3.3 inches) while the larger is 154 mm (6 inches).  Both rest in a single brown sheath.  It’s the handles I found especially interesting.  Each handle is chiefly dyed curly birch capped with elm wood.  The rakish cut of the handle butt provides a stop to prevent your hand from sliding off.

Puukko knives are so characteristic of Nordic countries, it’s hard to mistake them for any other knife.  Surely you recognize them?  Most puukkos have a slight shoulder but no ricasso because where the edge ends and the handle begins is where most power can be applied.  The blades have a long flat edge with no secondary bevel.  To sharpen, the bevel is place flat on the stone and then polished.


Puukko knives


Nor do puukkos typically have a guard to protect your fingers.  A puukko knife is primarily a cutting and building tool and not a tactical weapon. 

A classic blade would be the width of your palm, but you’ll find them 90-120 mm (3.5 to 4.7 inches) long.  This creates a market for both men’s and women’s puukko knives.  Women’s, (hey, it’s a sexist world) are typically shorter bladed for ease of food preparation.

In the Nordic countries, the puukko is an everyday knife that is used for everything from hunting, fishing, and garden work to opening boxes in the warehouse.  Despite being an everyday item, receiving a good puukko as a gift is considered a great honor in Finland.  Both Boy and Girl Scouts consider the puukko their scouting symbol as well as a handy tool.



In 1977 Finland banned carrying knives in public because, (wait for it…) they could be used as a weapon!  This law appears to be seldom enforced.  In my opinion, any law that depends on the personal outlook of a police officer is discrimination.

As an aside, the puukko is the only civilian item which can be openly worn as a part of a soldier's combat gear without breaching the regulations of the Finnish Defense Forces.  Because puukkos are traditionally considered to be very personal items, the military does not supply conscripts with them, and most bring their own with them.  It’s hard to imagine basic training with knives, but what do I know?

Excape!


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

secret edge
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.

Anthem knife
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.

Bugout in your Bug-out Bag
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.
