Carpenter PSF27 Knife Steel
Composition Analysis Graph, Equivalents And Overview

PSF27(Carpenter) - Carpenter alloy, confirms to the AISI D2 steel, made using Spray Form technology. Spyderco is using PSF27 in their Gayle Bradley bowie. SF offers uniformly distributed, smaller carbides, and while it isn't as efficient as PM process, still advantages over traditional ingot steel(uniformly distributed smaller carbides) are there.
