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.
CPM-20CV
Crucible's answer to M390 and chemically near-identical to it. Superb edge retention and corrosion resistance, slow to sharpen.
