The steel difference
420J2
Soft and very rust-resistant. Used almost exclusively for replaceable blades, where it is thrown away rather than sharpened.
Surgical Stainless
The scalpel-blade stock in Havalon, Gerber Vital and Tyto blades. Ground thin enough to be startlingly sharp and brittle enough to snap if twisted.
