Heard that "Schrade+" is/was schrade's premium metal for blades....but my vintage old timer sharpfinger is much more difficult to sharpen and holds an edge much better. What is "SCHRADE+"?
(someone suggested it's 440A). My zirconium carbide bit slides off the old Sharpfinger about like it does with the 8Cr13MbV of my CRKT knives, but will bite into the SCHRADE+ of my model LB7 folder (older U.S. made) with moderate pressure. (For what it's worth, the bit will peel metal off of Taylor's current China-production of a "SCHRADE Old Timer" pocket folder). Basically, just curious about the composition of SCHRADE+, and even more curious about the exceptionally tough metal of older SCHRADE fixed blades
