The best steel balances three things: how long it holds an edge, how well it resists rust, and how tough it is against chips and breaks. Cryo D2 is a tough tool steel with great edge retention. 154CM is a reliable stainless that is easy to sharpen. CPM MagnaCut is a U.S.-made steel that combines high toughness with excellent rust resistance, making it one of the best all-around steels available for EDC, outdoor, and tactical use.
