Is 440C superior to sub-zero quenched 420 in the area of making tactical knives in regards to corrosion resistance, breaking and keeping a sharp edge? Second question in regards to the same type of subject: anyone know much about a steel by the name of Sandvick 12SC27 used in Ka-bars Next Generation #1272 Fighter? Question number 3: Is VG10 a good knife making steel? And how about the lauded qualities of D-2? The reason I am asking these questions is because I have to choose just one knife and it is hard to find specific quality information on these particular steels. You can e-mail me @ the following address: wcboston2000@iwon.com // Thanks!

Wesley: Those are a lot of questions. With regard to the 440C vs. 420SS issue, provided that the quenching process produced >90% martensite, then 440C would have a higher hardness than 420SS and should hold an edge better, based on the higher hardness. The sub-zero quench is to transform untransformed austenite to martensite and can be applied to both 440 and 420. With regards to breaking, at equivalent hardness levels, both should possess equal resistance (or susceptibility) to fracture. D2 is not commonly used for knife blades probably based on their greater material cost and difficulty of fabrication as compared with the martensitic stainless steels. The other questions, we cannot answer with confidence. Hope this helps! David Hendrix The Hendrix Group Inc.
