CPM CruWear

Tough and wear-resistant at once, with more corrosion resistance than most tool steels. A hard steel to argue with if you can maintain it.

1-5 is a relative ranking drawn from published composition and hardness, not a lab measurement. Higher is better on every axis, and no steel is a 5 across the board — edge retention and toughness pull against each other.
