Some Blade steels

This is info taken from Spyderco for use in my article

Spyderco has experimented with new blade steels over the years. In 1994, Spyderco was the first company to use Crucible's S60V tool steel in a production knife and the first knife company to use H-1 steel in a folding knife. The blade steel used by Spyderco over the years include:

52100, a ball bearing steel used in the first run of the Mule project.

154CM a high end American stainless premium cutlery steel

8Cr13MoV, a Chinese stainless steel tempered at the Rc56 to Rc58 range and used in the Tenacious, Persistence, and Byrd lines of knives.

9Cr18Mo a higher end Chinese stainless steel used mostly in high end barbering scissors and surgical tools.

440C, a stainless steel, known for corrosion resistance and ease of sharpening.

ATS-55, a performance stainless steel similar to ATS-34 with the molybdenum reduced, used only by Spyderco for knife steels until the early 2000s

AUS-6

AUS-8

AUS-10, a Japanese stainless steel series made by Aichi with the same carbon content as 440C but with slightly less chromium.

BG-42, a high performance stainless steel formulated for ball bearings, often compared to ATS-34, which has similar properties.

D2, a high performance tool steel that has 1 percent less chromium than required to classify as stainless steel. Spyderco uses CPM's version of D2, which is a particle metallurgy ("powdered") version, not wrought. CPM-D2 is found in a sprint run version of the Military model.

G2, aka GIN-1. A Hitachi-made low cost stainless steel comparable to, but softer than, AUS-8. Generally hardened in the mid to high Rc 50s. A tough, corrosion-resistant steel.

GIN-2

H-1, a rust-proof steel, ideal for marine applications, because it substitutes nitrogen for carbon. Sharpens easily, scratches easily, and has good edge retention.

MBS-26: A Japanese [stainless] steel, very fine grained with high corrosion resistance used in the Catcherman and in most kitchen knives by Spyderco.

N690CO, an Austrian stainless steel hardened to the high Rc50 range. Currently found in Spyderco's Hossom knives and the recently disco'd Italian-made Volpe.

CPM S30V steel an American powder-metallurgy, high-carbide steel developed for the cutlery market.

S60V, (aka 440V, aka CPMT440V) A modern American super-steel that is wear resistant, but difficult to sharpen.

S90V (aka 420V), similar to Crucible's S60V but designed to be more wear resistant with a very high carbide volume and high vanadium content. S90V was featured in a sprint run of Spyderco's Military in 2008.

VG-10, a Japanese super-steel developed for the horticulture industry by Takefu, often hardened around the Rc60 range. Reported to have better corrosion resistance but less edge retention than S30V.

ZDP-189, a premium Japanese powdered super-steel made by Hitachi, hardened into the mid & upper Rc 60s, with very high carbide volume.
