Tinted rows are where these two differ.

The steel difference

Sandvik 14C28N

Developed with Kershaw. Tough, rust-resistant, and about as easy to sharpen as a good steel gets — the reason it dominates the value tier.

D2

Semi-stainless: enough chromium to resist spotting, not enough to be stainless. Big carbides mean long edge life and a coarse, toothy edge.
