While S90V holds an edge better than S30V, both are usually hardened to about 59–61 RC.ĬTS-20CP, Carpenter Technology's version of S90V, with slightly reduced chromium. Since then it has been used in several sprint runs in knives like the Manix 2 and Paramilitary 2. S90V was featured in a sprint run of Spyderco's Military in 2004.

420V), similar to Crucible's S60V but designed to be more wear resistant with a very high carbide volume and high vanadium content. Unfortunately the low level of toughness means that it can only be hardened to around 56 RC, causing the edge-holding performance to be diminished.ĬPM-S90V (a.k.a. CPMT440V), a modern American super-steel that is wear resistant, but difficult to sharpen. ĬPM-M4 (aka AISI M4), usually tempered to 62-65 HRC, a high-speed steel with combination of high carbon, molybdenum, vanadium, and tungsten for excellent wear resistance and toughness a powder-metallurgical, non-stainless steel.ĬPM-S60V, (a.k.a.

Sharpens easily, and has moderate edge holding and corrosion resistance.ĪUS-10, a Japanese stainless steel series made by Aichi with the same carbon content as 440C but with slightly less chromium.īG-42, a high performance stainless steel formulated for ball bearings, similar to ATS-34 (same composition, but with added vanadium), which has similar properties.ĬPM S30V steel an American powder-metallurgy, high-carbide steel developed for the cutlery market. ĪUS-6, similar in quality to 440a, used as a "budget" steel in early Spyderco models.ĪUS-8, a frequently used Japanese steel, which is known for taking a very fine edge, due to the inclusion of vanadium. The "Blue" refers not to the color of the steel itself, but the color of the paper in which the raw steel comes wrapped.ĪTS-55, a performance stainless steel similar to ATS-34 with the molybdenum reduced, used only by Spyderco for knife steels until the early 2000s. Often compared to AUS-8, but with slightly more carbon.ĩCr18Mo, a Chinese stainless steel used mostly in high-end barbering scissors and surgical tools.Ĥ40C, a stainless steel known for corrosion resistance and ease of sharpening.Īogami Super Blue (青紙スーパー), a Japanese high-end steel made by Hitachi.

The blade steel used by the company over the years include:ġ54CM an American stainless cutlery steelĥ2100, a ball bearing steel used in the first run of the Mule project.ĨCr13MoV, a Chinese stainless steel tempered at the RC56 to RC58 range and used in the Tenacious, Persistence, Ambitious, Resilience, Grasshopper, Kiwi3 and Byrd lines of knives. In 1994, it was the first company to use powder metallurgy in a production knife (in the form of Crucible's S60V tool steel), and the first knife company to use H-1 steel in a folding knife. Spyderco has experimented with new blade steels over the years. Additionally, the company claims that this was the first knife to feature a pocket clip on the right side of the handle. The firm began producing knife sharpeners in 1978 and produced their first folding knife, the C01 Worker, in 1981 this was the first to feature a round hole in the blade designed for fast, one-handed and ambidextrous opening, which is now the company's trademark. As they became more successful, they graduated from the bread truck to a truck and trailer. Spyderco's founder, Sal Glesser, and his wife Gail, converted an old bread delivery truck into a motor-home and traveled to shows.

#G CLIP SPYDERCO PORTABLE#
The first product Spyderco produced was the Portable Hand in 1976, this "spider-shaped device", was a series of angles, ball joints and alligator clips that helped people such as jewelers and hobbyists to work with small parts. The name Spyderco was coined after Glesser noticed that many high performance sports cars had 'Spyder' in the name which inspired the name Spyderco to signify high performance cutting tools.
