Gerber Parabellum


Gerber folding knife
Gerber Parabellum:  Prepare for war


The Gerber Knife Company has a funny origin story.  It’s not secret but I find it amusing.  It's not about making knives, it's about selling knives.

It’s 1939, Hitler fires the opening shots of WWII.  A few Americans are concerned.  Leo Szilard and Albert Einstein draft a letter to President Roosevelt about the potential to build an atomic bomb and advising him to create and fund a government research project on nuclear weapons.

Joe Gerber owns an advertising agency in Portland Oregon that has been in his family since 1904.  Christmas is coming and Joe wants to give special presents to his best customers.  He has David Murphy, a local knifemaker, craft 24 knives.

Somewhere, somehow Abercrombie and Fitch get their corporate hands on one and they want to sell them.

Joe, knowing advertising and business, starts Gerber Legendary Blades by ordering more knives from David.  Eventually David and Joe separate and my source claims David Murphy, despite his fame, dies bankrupt.

Over the years Gerber has employed craftsmen who went out and established names for themselves.  Both Pete Kershaw and Al Mar left and started their own companies. 

It is reasonable to say Gerber started the knife business in Oregon.  Over the years Gerber bought knife designs from a list of Who’s-who in the knife industry.  The list includes Bob Loveless, Blackie Collins, Fred Carter, Ernest Emerson, Bear Grylls, and local hero Rick Hinderer.

Folding knife, Gerber
The Parabellum is not a pocket size knife


In 1987 the Finnish company Fiskars bought Gerber Legendary Blades.  Fiskars is essentially a holding company whose main business concern is owning significant portions of other profitable companies.  Fiskars also owns the classic British company, Waterford Wedgewood, who is themselves a holding company.  Let’s not go down that rabbit hole.

From 1987 to 1994 Gerber made the Parabellum aka Black Bolt.  It was engineered to be one of the stoutest folding knives ever made.  And if you ever handled one, you would believe it.  It is reported that Blackie Collin designed the Bolt Action, the mechanism used to lock the knife open.  It takes a little force to unlock the blade.  That isn’t always a bad thing.

I ran into this one and despite the shadow on the back of the blade I bought it.  The edge looks factory and it comes with the duty belt clip.  The pouch can be reconfigured so the Parabellum can be slipped into it with the blade open like a sheath knife.


Discoloration on back of blade

The 4-inch flat grind drop point blade is over an inch and a quarter at the widest point and 11/64 of an inch thick.  The steel is probably 440C, the best of the 400 series.  At the time 440C was premium mid-level steel for knife making.

440C stainless contains:

                                    C   0.95-1.2%

                                    Cr  16-18%

                                    Mn and Si at 1% each,

                                    Mo  0.75%

The steel is magnetic so keep it away from your compass if you’re navigating by map and compass.

I think my Parabellum was carried and never used.  The pouch shows a little rust on the back snap and the cover snap seems to have been thumb polished.  The discoloration on the back of the blade appears to be confined chiefly to the portion of the blade not protected by the knife handle.  The handle itself doesn’t have a mark or scratch on it.

I’m going to leave it the way it is.

Spyderco K390 steel

It an Endura, one of Spyderco’s top selling knives. But this one is a little different . It has the new K390 steel blade. The flat grind blade is quickly becoming one of my favorite configurations. I grew up with saber and convex grinds but I’m won over by the flat grind. The absence of shoulders makes for easier cutting. If you’re slicing a wedge of Swiss cheese, you may want the shoulders as they push the materials apart and away from the knife. But you also encounter drag. Drag just means you have to put more force on the blade, and for most applications, forcing a blade is never a good idea. So I’m running some test because K390 steel sounds like a step backwards.

It’s not stainless. In fact a product insert warns you to protect the blade.

Bohler-Uddeholm list the following reasons to use their K390 Microclean steel:

  1. Good machinability because of uniform mechanical properties,
  2. Excellent grind ability even with deep engraving in the tool & die center,
  3. Uniform low dimensional change during heat treatment,
  4. Non sensitive against overheating or long soak times.
  5. Optimal EDM characteristic due to uniform carbide distribution.
EDM is Electrical Discharge Machining and it is becoming industries’ favorite machining and milling tool because it is efficient, economic, fast, controllable and computer-driven. Many of these steel properties, like dimensional stability are a big draw for knife makers.

The Chemistry also looks interesting.

  •  C  2.4%,
  •  Cr 4.2%,
  • Mo 3.8%,
  • V   9%, 
  • W  1%, 
  • Co  2%.

I should also note, new steels aren’t simply made by dumping elements together. Tempering, stress relief and hardening cycles have a major part in any production metal. Still, I find these numbers amazing, especially the 9% vanadium and 2.4% carbon!

Strictly speaking chromium levels should be around 11% to be classified as stainless. Chromium forms carbides that stabilize the microstructure, so in ordinary steels you need an excess of chromium to react with carbon and still have enough to protect against rust. Here you have vanadium to form carbides. So is there enough chromium to form the transparent chromium oxide barrier?  I don’t know.

Let’s play.

I’ve been cutting cardboard all week, I haven’t noticed any loss of sharpness. Today I cubed semi-frozen beef for a future chili dinner. I thought the knife handled better than many of the larger chefs’ knives or the smaller utility knives.
I sliced up some lemons and limes for summer drinks and the knife worked fine.

Tasted pretty darn good, too!



Afterwards I noticed the acid fruit left a start of a faint patina. I could lightly rub it out with a fine metal polish, but I think I’ll keep it. I like a working knife that looks like a working knife.
I increased the contrast slightly so you could see the patina. I'm wondering if it will wear away on it's own.

I think the K390 steel is going to be a winner. I haven’t had to sharpen it yet, but I have no doubt my Spyderco Sharpmaker is up to the job. I understand you’re going to see K390 steel in a lot of other Spyderco products. I also think you’re going to like it.

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.

The Finnish Butterfly


After college and having found a real job I discovered I had a little extra spending money.  I was entranced by a red handled folding knife that could be best described as a butterfly knife from Finland.  Of course I satisfied that itch.

Puukko Folder, Finish butterfly knife
Hackman Folding Puukko

The blade doesn’t have a tang stamp and the only identification is “Hackman Finland” molded into the red plastic handle.  The 3.75 inch blade is a saber grind with a small secondary bevel that forms the actual cutting edge. 

The blade is an unknown stainless steel.  I’ve had it for years and no evidence of rust has appeared, despite the minima care I’ve given it.  And the plastic has also held up quite nicely.  I filed a small choil in the blade to separate the edge from the ricasso.  It was thought, with some justification, that without the choil you would damage your sharpening stone by chipping away it’s edge. 

In retrospect I realize was all I really accomplished was to add a stress riser in the blade.

Hackman was a cutlery and cookware company founded in Finland in 1790.  Later it was bought by the Iittala Group.  In 2007, littala was swallowed by the Fiskars Corporation.  Fiskars never, in my opinion, understood the American knife market and even now needs to make up for lost ground.


Finnish, Folding knife, linkkupuukko
The folding Puukkko closed and latched

The Hackman butterfly knife was better known in Finland as Linkkupuukko, or "latch-knife". The marketing boys positioned it as a retkiveitsi or "camping knife" and later as ErƤpuukko or "wilderness puukko."  By now you should associating puukko with Finnish for knife.  I want to thank the unknow commenter who told me veitsi is Finish for knife.  They were kind enough to inform me thay puukko is a particular type of veitsi.

The Hackman story begins when Johan Friedrich Hackman was awarded the right to establish a trading house in the Hanseatic city of Vyborg.  He soon had a successful timber goods business on his hands, but like most businessmen he sought out new opportunities.  West of him was the territory now known as Finland.

In the early 1800s Hackman bought Sorsakoski – a small factory community in eastern Finland.  The purchase included a sawmill, flourmill and a brick factory.  Hackman’s cutlery business began in nearby Vyborg in 1876, headed by his son also Johan Friedrich Hackman.

Junior moved their entire cutlery manufacturing business to Sorsakoski in the early 1890s. The factory community was a mirror of Finnish society at the beginning of the twentieth century.  Companies like Hackman took full responsibility for providing basic services to their employees.  Sounds a little like the American coal mining companies and the company store, doesn’t it?

In 1902 Hackman began manufacturing new low-cost cutlery items forged from a single workpiece. The introduction of quality stainless steel in the 1920s revolutionized the entire cutlery business.  By the 1960s design legends like Kaj Franck and Bertel Gardberg had designed iconic cutlery collections for Hackman.

The black handle version of the knife seems to have a sordid past or excellent present day marketing.  There are rumors, highly unsubstantiated rumors, that CIA agents were issued the knife for Vietnam.  If anyone has any real knowledge I’d sure like to hear from you.

This makes some limited sense.  The knife isn’t made in the USA and being caught with one might not brand you as an imperialistic agent.  The mechanism is simple and robust, perhaps perfect for undercover work.  Being inexpensive, ditching the knife if you were being followed or mouse-trapped didn’t require a huge sacrifice on your part.

However, it isn’t likely you can call up the CIA and speak to the quartermaster and expect to get a straight answer.  That’s where the marketing comes in.  It’s easy to say on ebay that the knife is from the CIA / Vietnam issue era.

Recently, Spyderco added some credibility to this story in their April Newsletter:
" While the Finnish Hackman Camp Knife, a balisong-style folder rumored to have been issued by the CIA in Vietnam..."

There’s a story here and perhaps one day we’ll know it in its entirety. 

Post script:  At the Novi, MI April 2023 show, I saw a black handled Hackman butterfly knife.  Like the red one, the blade did not have a tang stamp or other markings.  But the knife wasn't completely sterile as I had expected.  Impressed on one side of the black handle, where the words Hackman Finland in very small letters, about half the size as the embossing on the red handled knife.

The knife was in very bad shape and I now have buyer remorse that I didn't buy it.  

Does this resolve the CIA story.  No, with out some province from someone who was issued or worked with a agent and saw the knife, the question remains unanswered.

Damn it, I should have bought the knife!
