CPM-20CV
Crucible's answer to M390 and chemically near-identical to it. Superb edge retention and corrosion resistance, slow to sharpen.
- Typical hardness
- 59-61 HRC
- Edge retention
- 5/5
- Toughness
- 2/5
- Corrosion resistance
- 5/5
- Ease of sharpening
- 2/5
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.
