When it Rains.....


Ken Onion made his first knife in 1991 and hasn’t looked back.  He is a prodigious innovator holding 36 design patents on different items including locks, mechanisms, and knife designs.

Ken Onion Designed Rain Paring Knife


And frankly, I really love his designs.  So when I had the chance I picked up a kitchen knife from his Rain collection from Chef Works.  The instantly visible, the most striking aspect of the knife is the highly polished blade with a textured rain drop pattern.  Hence the name.  The pattern on the blade is designed to reduce food drag caused by surface tension and drag coefficient by creating multiple pockets of air.

Beats me.  I know drag coefficient is used in calculating friction forces which resist movement. I’m sure if you spent 8 hours a day cutting food, you’d want reduced food drag too!

Reverse paring knife
The blade is on top


The business end is a 3 inch reverse paring blade made from Carpenter’s DBZ-1 stainless steel.

DBZ-1 isn’t made from exotic elements.  The bulk of it is iron.  Carbon is between 0.6 and 0.75% with chromium falling in line with 12.5 to 15.3%.  There’s only 0.75% molybdenum  and a smattering of other elements.  The key to this martensitic steel is that it is designed to produce a network of fine carbide particles throughout the steel.  This produces a steel that takes a remarkable edge and holds it.

The most interesting part is the reverse edge.  The curved blade has the sharp, business edge on the top of the blade.  You need to be careful gripping the knife, because the finger grooves are on the opposite side from the edge.  I can’t tell you how many times I wanted to put my thumb on the razor sharp edge.  Just be real careful with this one.

They even warn you in the box.


The handle is shaped from G-10, a high-pressure fiberglass laminate.  It is made by stacking multiple layers of epoxy resin soaked fiber glass sheets and curing under high compression.  G-10 is the toughest of the glass fiber resin laminates.  It is almost indestructible.

This is a glamorous knife.  The blade catches the light and winks as you move it.  The handle with it’s finger grooves feel really good.  It was Blade magazine’s Kitchen Knife of 2013.
But you better watch that blade.  You may not shoot your eye out, but you’ll cut you finger off.

Bingham Knife

The knife caught my eye at a knife show and it came home with me.  But what did I get?  Well, it always starts with tang stamp and a reference book.  “W. Bingham Co  Cleveland O” was all I could read.

Mystery W. Bingham Knife


Cleveland at the turn of the 20 century had a glowing reputation as a hardware mecca.  There were four major distributors, one of which was The W. Bingham Co, which was one of the Midwest's largest hardware concerns.  It was founded when William Bingham and Henry Blosson bought out the hardware stock of Clark & Murfey in April 1841.

They opened their own store at Superior and W. 9th street and later expanded by erecting a new building nearby in 1855.  They also incorporated as the W. Bingham Co. in 1888.

In 1915, Bingham discontinued its retail operations and built a new wholesale warehouse at 1278 W. 9th St.  Although Bingham expanded its line of goods, its major business always remained hardware supplies and conducted business over 12 states. On 15 June 1961, Bingham closed its warehouse, but a group of Bingham officers, headed by Victor E. Peters, acquired the company's industrial division and renamed it Bingham, Inc.  Eventually the company stopped making industrial tools and became a distributor only.  Ownership traded hands with brokers and money managers and was finally bought by Formweld Products Co.  Some form of the company remains in operation in Solon where it continues to distribute tools to area manufacturers.

The blade has been polished but retains the rust pits.  The jog in the handle can be seen.

The first google reference I found was for a forged and fraudulent W. Bingham Co, knife. That didn’t give me any warm and fuzzy feelings.  The second was an Etsy ad for a $300 Bingham knife.  It was, as all Etsy products will tell you, rare and unique. 

A lot of distributors carried knives with their tang stamps which were made for them, not by them.  Cutlery companies exist to sell knives with your tang stamp.  One only has to look at early Spyderco’s made in Seki City.  Spyderco didn’t build a factory, they hired some to make it for them.  This is an honorable business practice, if properly identified.

Not a sealed end like doctor knives


As for the type of knife, well that’s still up for discussion.  It has squared butt, like a doctors, but it is pinned in place and not solid like a doctors knife.  About half way up the handle the entire handle takes a little jog sideways in the plane of the handle.  It’s not quite like a gunstock, because both sides jog and it’s a very small jog.  The main blade is a thin flat blade with a shallow false edge.  This style is often referred to as a long spear or physician blade.  The second blade is small despite the large channel it sits in.  Both blades open from the same end like a trapper, but the blade and knife handle are wrong, wrong, wrong for a trapper.  

Not a Trapper!


It’s like, in my unfounded opinion, you wrote up a description of what the knife should look like and someone else drew the sketch and made it.

The knife is lined with two brass side scales and a brass center scale.  The scale covers, I suspect, are a celluloid swirl of white and olive green.  Each blade has its own back spring. 

The blades have seen better days.  One of my common remarks is, if owners had just wiped down the metal surfaces with a drop of 3 in 1 oil… but they didn’t.  The blades and springs had rusted and someone scoured them rust free and ruined the collectable nature of the knife.  Even the back of the springs has been polished shiny.  As much as I hate rust, these scoured blades, so shiny and pitted just look wrong.  The defiler would have done better to just oil and carefully rub off the crusty rust and not gone after the pitted rust.

Each blade has it's own spring

I don’t think the knife was made by W. Bingham Co.  I think it was made for them.  It’s a link to Cleveland and part of the confusing history of knife making when companies were bought, sold, reacquired.  Today we expect some longevity in companies, but even that isn’t true.  New companies emerge and old names are sold.  Companies that were silent jobbers have launched their own brand using the experience they have gained making knives for other companies. Established companies use the excess capacity of smaller companies struggling to get a foothold, to boost their production or try out a new idea cheaply.  Names and brands are not guarantees if they were ever.

Treasures in the Drawer


I’m settled in for the next week at home.  I was cleaning a drawer and guess what?  I found two knifes I had almost forgotten about.

It was 1990 and I was reading Larry Niven’s Protector.  Larry represented the changes we experience in old age, due to a missing environmental agent, as an incomplete transformation to a superior being.  One of the attributes was skin so tough, so armored it could turn a bronze knife.  I wanted a bronze knife, but even bronze was expensive on my budget.

The bronze has tarnished a bit and it isn't very sharp, but at one time this was atomic bomb of the era

I was also interested in the Spanish navaja.  These are classic Spanish folding fighting and utility knives.  The classic knife used a set of pinion teeth which when opened produce a characteristic clicking sound.  Hence the nickname in some quarters, of cucaracha or cockroach.  Navajas came in many sizes and the larger ones were used for dueling.  It was said the sound of this knife opening in the darkness would make a brave man blanch.  Pretty cool, yes? 

Small navaja
Atlanta Cutlery made museum quality replicas and sold other knives as well.  Their catalog is part of a select group of magazines I call knife porn.  The color photos were great, as were descriptions of hard to find knives.  I used to dog ear pages to find my favorites faster.  Prices lists were the worst part.  One 1990 dollar had the purchasing power of $2.00 today.  

Still I found what I wanted: a small 1.75 inch bronze blade folder and a 3 inch blade navaja.

They originally had a ring attached to the pivot to open the lock.  that evolved in to the little metal tab.


The bronze bladed knife was described as a sandalwood folder costing $27 and the navaja priced in at $16.95.

I never used either.  Everyone swapped out their bronze weapons as soon as iron became available and even with the problem of rusting they were happy to do so.  I keep my bronze knife in a little caddy with cuff links.  It really belonged on a pocket watch chain.

The navaja was a disappointment.  Despite being made in Spain, it didn’t have the click and clacking noise I was interested in.  It too, doesn’t have a maker’s mark.

While now as a collector I am happy to own them, at the time it was one of many little lessons that wanting is sometimes better than owning.

Marttiini – Not a Drink




As found Marttiini Explorer, fixed blade
Marttiini Explorer: It said so on the blade

There is a universe of quality knives that are largely unknown to the American buying public.  One such is the Marttiini brand.  So when I saw the brown leather sheath stamped ‘Marttiini’ among the rest, I knew what to grab.  Their motto is “Created by Artic Evolution” and in that harsh unforgiving environment your knife may be the difference between surviving or dying.  Pick your tools wisely young Jedi.  Marttiini knives are still manufactured at the Arctic Circle.

As found, Marttiini, Explorer
The sheath, especial the closing flap is a little chewed up


The Marttiini Story

Janne Marttiini was born on May 2nd, 1893 in the small village of Kierinki.  It is a harsh environment of short summers and long, cold winters on mountain ranges older than life. In 1928 Janne founded J. Marttiini’s Knife Factory Ltd. on Vartiokatu Street in Rovaniemi.  With the knife user in mind, he began to create beautiful, high quality knives to exceed the harshest conditions imaginable.

He sold his knives throughout the region and their sales created prosperity and opportunity.  As demand for his knives grew Janne hired more and more people and the number of employees grew steadily.  There was worldwide demand for high quality knives, and Marttiini exports grew driven by their quality.

Janne’s son, Toivo Marttiini, led the company in the 60s. Toivo’s younger brother, Lauri Marttiini, took the reins of leadership in 1975.  In 2001 Mrs. PƤivi Ohvo, was appointed to the office of CEO.  In 2005, Marttiini’s family sold the entire capital stock of Marttiini Ltd. to Rapala VMC Corporation.  And throughout that time quality knives rolled off the production lines and most of us are unaware of it.

My Marttiini

So what knife did I have?  The blade is vibro etched by hand with INOX - Explorer Knife - Made by Marttiini – Finland.  I could find images, but not much more.  Fortunately the internet came to my rescue.

Hanna Helin at Marttiini answered my e-mail and provided the information I was searching for.  Thanks Hanna!

The Explorer was a line of knives with different blade lengths, 7, 9.5 and 11.5 centimeters.  That would be about 2.75, 3.7 and 4.3 inches long.  The handle is rosewood.  The blade is simply identified as a stainless chrome steel.  The knives were manufactured from the 1980s to their demise in 1996.  Mine is the smallest blade, 2.75 inches with a rosewood handle.

All stainless steel contains chromium.  Chromium forms a semi-flexible, transparent oxide film that prevents rusting.  Excess chromium reacts with the carbon in steel to form very hard and very tiny chromium carbides.  These carbides, despite their name are closer to ceramics in structure and give steel many of its go-to properties.

The knife and its sheath have seen some rough handling.  I didn’t want to give the knife a complete make-over.  While it is a popular descriptive phrase and it makes me laugh, both the knife and sheath have a patina of use I wanted.

The leather sheath needed a cleaning so a mild hand soap and terry cloth rag cleaned the leather and I let it air dry.  I followed it by a polishing with a brown wax polish and buffed the leather.  It still has the stains and burn marks but it looks better.

I like the pressed designs in the leather.  The sheath has a pressed composited slipped down in the blade area to keep the edge from cutting through and biting you.

I had previously purchased a sharpening gauge to determine the sharpening angle of blades and put it to work.  

And it opens beer bottles too!!
The best match, I found, was at 20 degrees.  I found an open spot on the garage work bench and set up my Ken Onion Work Sharp Sharpener.  So what grit belt should I use?

After an initial run on a worn out medium grit belt I selected three grades, coarse, medium and fine.  Then I got out my secret sharpening weapon: a black magic marker.

belts of grit. Work Sharp
You can see the Explorer on newspaper next to my secret weapon, the black magic marker 

If you don’t use one I recommend it.  Just color the edge you’re sharpening and each pass will tell you if you are accomplishing what you want.  Clean the residue off the blade with a little shop acetone or nail polish remover.

It took about six passes with the coarse before I had a wire edge on one side of the knife and six on the other to remove it and create a new one.  By following with the medium and fine I walked the edge over to the sharpness I wanted.  I stropped with several sheets of newspaper on a flat surface and it was sharp!


Yes, the polished sheath does still show the patina of wear and use.  I don't know, I find it strangely honest and what I want in any knife is honesty.
I thought about using some 1000 grit wet-dry paper to knock down the rosewood handle finish and reseal with linseed oil, but I elected to stay, at least for the time being, with the original finish on the grip.


Condor knife, Marttiini Condor
The Marttiini Bowie Condor nested deep in its sheath

Unfortunately this knife isn’t available, but others are.  I like their Bowie Condor, another totally icey Marttiini knife.  The black leather sheath has a plastic liner to reduce stab through and protect you if you fall in the field.  The knife sits deep in the sheath preventing accidental pull-out by clothing or grabby summer weeds.  The belt loop sports what I think is a button slit, but I have never been able to confirm it.  I suspect a button sewn just behind your hip, so the belt passes over it would secure your knife in the same place.  The button holds the knife in the same place and the belt secures it to you.  Then when you are searching for the knife under your arctic parka or under multiple layers of wool, fleece and water-proofed canvas you know exactly where the knife is.

I've gotten some very nice reports from users in the field for ease of handling and sharpness combined with edge retention.

In any case I really like my Marttiini and recommend it.
