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!

Delica in the Key of K390

 Back before it started, the old gods came together for a meal and to brag about what they contributed the newly forming reality.  Loki/the Coyote/the Trickster was especially gleeful.

“I gave them iron and carbon.”

“So?”

“They mix to form an alloy.  Too little carbon and the steel formed will be soft and useless.  Too much and it becomes brittle cast iron.  If they add the just right amount they get properties all over the place.  And it still rust!”

The old gods thought it was a clever joke on the humans.  All but one, Vulcan/Brokkr/the Master Forger.  Without steel, how could they build things, he wondered.  He crept off and threw a hand full of elements, and perhaps more important, undiscovered knowledge into the mix.

Thanks, Vulcan!

Delica in the key of K390


I just got Spyderco’s K390 Delica and it is quickly becoming my favorite pocket knife.  I really like the Delica/Endura line.  Back in day, I used to fly with two Delicas and airlines had no problem with that.  Even back then those sealed packages of peanuts were hard to open!

K390 steel Delica
I found I could always depend on Delicas and the K390 is no exception!

I’m not really a super steel fan.  Almost every steel the national brands use is hardened and tempered to bring you good performance.  But right now, for a working knife, I suggest you look at K390 steel.

K390 is a tool steel with interesting properties.  Right now, Spyderco is one of the few companies making knife blades with it.  Chemical analysis would find:

Carbon: 2.47%  (Wow!),

Chromium: 4.2%,

Molybdenum: 3.8%,

Vanadium: 9%,

Tungsten: 1%,

and

Cobalt: 2%.

The rest is iron.

It isn't a gamble with Spyderco's four position clip 


 Each of these elements affect the basic crystalline structure of the steel and its properties.  The metallurgy is more complicated than you can imagine.  In its simplest form, chromium and vanadium form small hard carbides that contribute to edge properties.  The remaining elements alter the metallurgical properties.

It doesn’t take a lot of study to realize K390 isn’t a stainless steel.  It is a hard-working tool steel.  And no, you just can’t add another 8-9 %of chromium and make it stainless.  Well, at least if you want to retain the other properties, most of which go unnoticed by the user.  Science tells us why, but that’s just an understand of how the universe work.  For the real reason you’ll have to ask the Trickster.

I like the coarse jimping on the FRN handle

K390 was submitted for an Austrian patented by Bohler in 2002.  Bohler wanted a steel to compete with Crucible’s CPM-10V.  It is not a new steel and gradually found a place among knife makers.

Like all steel, the properties have a give and take aspect and are affected by heat treatment.  K390 is one of the top tier steels with excellent toughness and slicing edge retention.  That is the take.  The give is corrosion resistance.  You need to take care of your steel, wipe it dry and use a good oil.  Spyderco incudes a little handout on caring for the steel.  I’d read it if I was you.

Heading out for Deer camp?  Make sure you take a Spyderco Delica in K390.

Which oil?  There are really two options, food safe and non-food safe.  I tend to lean toward food safe, but I’ve used  penetrating oils too.

I like my new Delica with K390 steel.  Currently all of Spyderco’s K390 steel come with a unique blue handle.  Mike Janich tells me he calls it K390 Blue.

The Delica has a flat grind, which contributes to it’s cutting powers.  Not having shoulders, like the saber grind or it’s brother, Scandi, it doesn’t have to push material out of the way to keep cutting. 

Delica  K390 steel
I don't always go off the beaten path...  But when I do it's with a Delica  in K390 steel

The grips are FRN or fiber reinforced nylon.  The fibers, to the best of my knowledge are short glass fibers which strengths the nylon.  The grip sports bidirectional texturing which radiates outward from the center of the handle.  The texturing is strikingly attractive and more importantly, provides increase purchase with wet and slippery hands.

The blade has the trademark Spyderco hole.  I don’t know which is more uniquely Spyderco, the fat tick-like spider logo or the functional opening hole.  In either case, the thumb hole was genius!

One of the major improvements in the knife world is movable clips.  Sal Glesser, Spyderco founder, is credited with the pocket clip he called "Clip-it."  Later versions of Delica and Endura had a reversible clip.  Eventually most Spyderco folders have four-position clips.  I simple love that options.  Most of my knives are carried tip up right hand, but I’ve been known to set up a knife for tip up left-hand carry.  While this may seem trivial to you, this allows Spyderco to be essentially an ambidextrous knife.  Its estimated 10% of the world’s population is left-handed.  Being able to operate a pocket knife with either your left or right hand is amazing.  Unfortunately, many companies have not caught on to this pocket knife innovation.


For me the ability to make a fire by shaving fir sticks and scrapping Birch bark in the touch stone to all knives.  Spyderco Delica have never let me down.

Spyderco’s  K390 Delica cuts.  I cut seatbelt material.  No problem.  Opened packages and bags, cut string and rope.  I shaved feather sticks to build a fire, my personal touchstone of knife performance.  Carboard trembles in its presence.  What a knife!

The suggest retail price is $176.  Right now, all I’m finding on Spyderco website is the full serration:

https://www.spyderco.com/catalog/details/C11FK390/1885 

I suspect if you look about, you’ll find the plain edge on line.

Finnish Delight

 Iisakki Järvenpää Puukko

I recently picked up a lovely dual Finnish puukko set made by Iisakki Järvenpää Osakeyhtiö.  The puukko set is a traditional dress knife pair with a painted red handle and brass fittings.  The two blades are engraved with the founder's signature, Iisakki Järvenpää.

I have recently discovered an interest in puukkos.  I admire the refinement and practicality of a knife designed to survive in the brutal arctic environment.


Puukko knives
A Puukko by Iisakki Järvenpää Osakeyhtiö

A puukko is a general-purpose belt knife with a single curved cutting edge, solid hidden tang, and usually a flat spine.  Military models of puukkos have been popular in the Russian criminal underworld under the name "Finnish knife" or finka since the 20th century. 

Puukkos don’t have a ricasso (a section of the unsharpened blade nearest the handle) because this is where the most power can be applied.  While finger guards are uncommon (it is a cutting tool, not a stabbing weapon), puukkos intended to be used in wet or slippery environments will have some form of guard or grip enhancement carved into the handle.

The short knife is 5.75 inches long, while the larger one is about 8.5 inches.  They occupy a leather and brass sheath.  The front is partially painted/coated in red to match the knife's grip.

This set appears to be part of traditional ethnic dress, needing only a Helavyö belt.  The Helavyö is a leather belt decorated with several metal plates (or "hela"s).  The belt is an accessory worn by men and women in traditional garb but only by men in non-Karelian attire.

The Karelian people are from an area in Northern Europe with historical significance for Russia, Finland, and Sweden.  Often, a trinket of some shape hangs from each metal plate.  The pendants are a pretty decoration; they show off the wearer's wealth.  As a bonus, they are reported to keep the devil away.

The company’s founder was Iisakki Järvenpää.  He was born on January 7, 1859.  From an early age, Iisakki was curious and thirsty to learn everything new.  He practiced his reading and writing skills on his own initiative.  While writing, he practiced not only the writing skill itself but also his penmanship.  His attraction to uncompromising and meticulous visuals is reflected in his knives and writing.  Iisak's signature is the company logo.


Red handled Puukkos

The Iisakki Järvenpää Company was founded in 1879 and is the largest manufacturer of knives in Kauhava, Finland, a well-known town with a long and rich history of knife making.  He had to learn everything from forging to metal polishing.

Self-taught, Järvenpää made simple work knives, but in 1888 he made a gift knife for the hereditary prince of Russia and the future emperor Nicholas II.

Because of the gift knives' impact, Iisakki received the title Keisari's knifesmith, which was entered in the church's books in 1889.  Keisari's blades had the lion coat of Finland carved into the handle and the emperor's crown on top of a lion.  The imperial thanks from future emperor Nicholas II received a lot of attention in newspapers nationwide, which led to a widespread increase in the demand for Iisakki’s knives.

Despite this success, his knife business grew slowly.  Wanting more for his family, Iisakki gave up 20 years as an independent craftsman and became a foreman at the newly founded knife factory in Kauhava.  Discovering the company had lied to him about benefits, he resigned from his position and re-established his own knife shop on February 15, 1904.  From this point, Iisakki's company became known as Iisakki Järvenpää Osakeyhtiö (Limited Company).

Iisakki died on March 6, 1929, but his company continues, and the knives are made by hand in Kauhava, Finland, from locally sourced materials.  You can find out more at: https://www.iisakkijarvenpaa.fi/us/story
