VG-10
VG-10, a premium Japanese super-steel developed for the horticulture industry by Takefu. Considered a good balance of corrosion resistance, edge retention, and toughness, but is not a "high carbide" steel [confirmation needed]. According to Sal Glesser: "Continuous edge testing on a CATRA consistantly shows VG-10 to be superior in sharpness and abrasion resistance to ATS-34 and ATS-55." Often hardened around the Rc60 range. Reported to have equivalent or better corrosion resistance (see MacTech's tests) but less edge retention than S30V. Considered easy to sharpen for a super steel. Overpowered edges tend to bend rather than chip, which is preferred by many. Widely regarded as a well-balanced steel, with high marks for edge-holding, toughness, and corrosion resistance. Currently found in many more Spyderco knife models than any other steel. Taken from the spyderco.com forums and reprinted with kind permission from author [1]
