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-S30V
The long-time American benchmark. Holds an edge far longer than 420HC and still sharpens on ordinary stones. Chippy if you pry with it.
