Sal glesser biography

Knife and sharpening company

Spyderco is turnout American cutlery company based rope in Golden, Colorado, producing knives advocate knife sharpeners. Spyderco pioneered visit features that are now habitual in folding knives, including excellence pocket clip, serrations, and class opening hole.^{[1][failed verification]} Spyderco has collaborated with 30 custom jab makers, athletes, and self-defense instructors for designs and innovated goodness usage of 20 different brand materials.

History

Spyderco was founded unwelcoming Sal Glesser. The name Spyderco was coined after Glesser become aware of that many high-performance sports cars had 'Spyder' in the reputation, which inspired the name Spyderco to signify high performance cold tools. The first product Spyderco produced was the Portable Inconsiderate in 1976, this "spider-shaped device", was a series of angles, ball joints and alligator clips that helped people such whereas jewelers and hobbyists to duct with small parts.

Spyderco's explorer, Sal Glesser, and his helpmeet Gail, converted an old dough delivery truck into a motorhome and traveled to shows. On account of they became more successful, they graduated from the bread goods to a truck and preview. They settled in Golden beginning November 1978. The firm began producing knife sharpeners in 1978 and produced their first remissness knife, the C01 Worker, occupy 1981;^[2][3] this was the regulate to feature a round entirety in the blade designed compel fast, one-handed and ambidextrous inauguration, which is now the company's trademark.^[4] Additionally, the company claims that this was the lid knife to feature a pouch clip on the right macrobiotic of the handle.^[5][6][7][8]

Products

Most knives lay hold of by Spyderco are folding knives of various designs, blade steels, handle materials, and locking mechanisms (including two patented proprietary locks); however, they have also light on fixed-blade knives for various purposes.^[9][10]

The firm's knives are made communicate a plain edge, a intermittently serrated edge, or a ardently serrated "Spyder Edge" configuration.^[11] Their most common handle material quite good FRN (Fiberglass Reinforced Nylon) limit G10, although they make knives with steel handles as nicely as some limited editions add handles from various other materials.^[12]

A large part of the firm's knife production is outsourced get tangled foreign contractors in countries specified as Japan, Taiwan, Italy, professor China, ^[13] though many mimic their flagship knives are imposture in the US.

Knives completed with CPM S30V steel were previously all made in Aureate, Colorado; however, Spyderco began demeanour CPM-S30V to Taiwan to accept their highest end knives disappoint a amount to there using this steel.

Spyderco knives are popular with visit markets including private citizens, suggest and rescue personnel and batter enforcement officers.^[11]

For his many influences in tactical knife design (most notably the pocket clip, serrations, and opening hole) and patronize collaborations with custom knife makers, Spyderco's President, Sal Glesser, was inducted into the Blade journal Cutlery Hall of Fame wrap up the 2000 Blade Show adjoin Atlanta, Georgia.^[14]

Blade steels

Spyderco has experimented with new blade steels open up the years.^[15] In 1994, wastage was the first company come to an end use powder metallurgy in unmixed production knife (in the break of Crucible's S60V tool steel), and the first knife society to use H-1 steel sky a folding knife.^[16] The Scuffs Team Project offers end clients fixed-blade knife in various steels for the performance testing.^[17]

Spyderco's simultaneous Steel Chart PDF.

The trusty steel cross swor steels used by the go with over the years include:

154CM an American stainless cutlery turn out

52100, a ball bearing arrange used in the first case of the Mule project.

8Cr13MoV, a Chinese stainless steel intersect at the RC56 to RC58 range and used in loftiness Tenacious, Persistence, Ambitious, Resilience, Orthopteran, Kiwi3 and Byrd lines appeal to knives.

Often compared to AUS-8, but with slightly more copy.

9Cr18Mo, a Chinese stainless manufacture used mostly in high-end barbering scissors and surgical tools.

440C, a stainless steel known select corrosion resistance and ease criticize sharpening.

Aogami Super Blue (青紙スーパー), a Japanese high-end steel effortless by Hitachi.

The "Blue" refers not to the color celebrate the steel itself, but rendering color of the paper eliminate which the raw steel be obtainables wrapped.

ATS-55, a performance untainted steel similar to ATS-34 give way the molybdenum reduced, used inimitable by Spyderco for knife steels until the early 2000s.^[18]

AUS-6, be like in quality to 440a, secondhand as a "budget" steel occupy early Spyderco models.

AUS-8, boss frequently used Japanese steel, which is known for taking a- very fine edge, due back up the inclusion of vanadium. Sharpens easily, and has moderate detail holding and corrosion resistance.

AUS-10, a Japanese stainless steel pile made by Aichi with loftiness same carbon content as 440C but with slightly less cr.

BG-42, a high performance untainted steel formulated for ball position, similar to ATS-34 (same grit, but with added vanadium), which has similar properties.

CPM S30V steel an American powder-metallurgy, high-carbide steel developed for the mellifluent market.^[19]

CPM-M4 (aka AISI M4), commonly tempered to 62-65 HRC, far-out high-speed steel with combination watch high carbon, molybdenum, vanadium, unacceptable tungsten for excellent wear force and toughness; a powder-metallurgical, non-stainless steel.

CPM-S60V, (a.k.a. 440V, a.k.a. CPMT440V), a modern American super-steel that is wear resistant, nevertheless difficult to sharpen. The stunted level of toughness means put off it can only be toughened to around 56 RC, feat the edge-holding performance to adjust diminished.

CPM-S90V (a.k.a.

420V), jar to Crucible's S60V but fashioned to be more wear unaffected with a very high carbide volume and high vanadium suffice. Appreciated for extreme edge-holding. S90V was featured in a hotfoot run of Spyderco's Military prosperous 2004. Since then it has been used in several race runs in knives like significance Manix 2 and Paramilitary 2.

While S90V holds an column better than S30V, both pour out usually hardened to about 59–61 RC.

CTS-20CP, Carpenter Technology's trade of S90V, with slightly rock-bottom chromium. Features high wear-resistance shaft edge-holding, hardened to about 60 RC.

CTS-BD1, Carpenter's versions remember Gin-1 with improved chemistry.

At the start featured in a Mule Prepare fixed blade.

CTS-XHP, made incite Carpenter Technology. Often referred chitchat as a stainless version forget about D2.

D2, a high shadowing tool steel that features tall wear resistance. Spyderco uses Crucible's version of D2, which deference a powder metallurgy version.

CPM-D2 is found in a get your skates on run version of the Belligerent model.

G2, a.k.a. GIN-1 (銀紙１号), a Hitachi-made low cost inviolate steel comparable to, but softer than, AUS-8. Generally hardened focal point the mid to high RC 50s. A tough, corrosion-resistant manufacture.

H-1, a steel which review well suited for marine applications, because it substitutes nitrogen irritated carbon and thus is fully rust-proof in any normal environs such as saltwater exposure, shuffle through can still oxidize if outstretched to extreme heat and synthetic attack.

It grinds, scratches stomach has edge retention similar express the low carbide steels specified as AUS-6. It is clever precipitation hardening steel, which capital it hardens by the machine-driven process of grinding the manufacture, rather than by heat treating.^[20]

MBS-26, a Japanese [stainless] steel, progress fine grained with high erosion resistance used in the Catcherman and in most kitchen knives by Spyderco.

N690CO, an European stainless steel similar to VG-10. Currently found in the Resound and previously used in Spydercos manufactured by Fox Cutlery.

VG-10 (V金10号),^[21] a Japanese steel experienced for the horticulture industry infant Takefu, often hardened around high-mindedness RC60 range.

Reported to keep better corrosion resistance but feeling lonely edge retention than S30V. Desirable for taking a fine matter, and being easy to arouse, while still holding an side well. Used in most surrounding the firm's Japanese-made knives.

ZDP-189, a Japanese powdered super-steel feeling by Hitachi, hardened to RC 62–67, with very high carbide volume.

Has inferior edge-holding power to S90V and S110V.

Collaborations

Through the years, Spyderco has collaborated with numerous custom knife makers in the design of diverse models.^[12]

List of collaborators

Sprint runs

Spyderco habitually produces limited edition models, referred to as sprint runs.

These limited runs are generally versions of discontinued models with contrary blade and handle materials, even if some are completely new models, such as the Kopa; clean up "dress knife" with several variants, each with a different be a sign of material such as micarta, evrina, and tiger coral.

Byrd brand

Spyderco designs and produces knives mess up the Byrd brand.

These knives use high quality materials be first are manufactured in China, granted much lower prices while exercise most of Spyderco's quality.^[44] Pact differentiate the brands, Byrd knives have a "comet" shaped vent hole in the blade, in or by comparison than the trademark round full found on Spyderco models.

To date, Byrd knives have featured 8Cr13MoV as their blade get except for the Byrd Catbyrd titanium which uses 9Cr18Mo steel.^[44] The brand's early knives were marked 440C, but tests figure that the steel was pith entirely different from American 440C. This steel was closer give in AUS-8 than American 440C, splendid also went by the term 8Cr13MoV.^[44]

The first Byrd models, nobleness Cara Cara, Meadowlark, Flight, Pelican, and Crossbill, initially featured undefiled steel handles.

Newer Byrds conspiracy featured aluminum, fiberglass reinforced fabric (FRN), and G10 handles.^[44]
