Ultimate Knife Steel Comparison Table
Survival-focused ratings for popular blade steels used in real-world knives.
This table is designed as a quick-reference map of common knife steels for survival use. Ratings are approximate and
based on typical heat treats for field knives, not lab-perfect numbers. Use it to compare options and match your steel
choice to the kind of world you expect to survive in.
In a stable world, steel specs are trivia. In a broken world, they decide whether your edge keeps cutting after everything
else has failed.
Type: C = Carbon, T = Tool, S = Stainless, P = Powder, R = Rust-resistant
Scores (1 – 10): higher is better
