Tinted rows are where these two differ.

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.
