CPM-3V

The toughness champion. Chosen when a blade has to be batoned or pried and breaking is unacceptable. Keep it oiled.

Typical hardness
58-61 HRC
Edge retention
3/5
Toughness
5/5
Corrosion resistance
2/5
Ease of sharpening
3/5

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.
