Ka-Bar's 1095 with chromium and vanadium added — a little more wear resistance, still very much a carbon steel.

Typical hardness

56-58 HRC

Edge retention

2/5

Toughness

4/5

Corrosion resistance

1/5

Ease of sharpening

5/5

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.
