Peters! if you're near I can lend you my knife collection....
I have steel!....
Randall knives use 440B (carbon, manganese, chromium)
Buck knives uses ATD34 (also carbon, manganese, chromium but with different percentages)
Cheap good knives use Carbon 420..
Spyderco knives uses S30V (Carbon, Chromium, Moly, Vanadium)
You have some knives? Some knives have the steel type stamped on the heel or bolster of the blade like "Carbon 420" or just "420" but.... can you bring them to school?
