Carbon steel

C100S Carbon

The carbon steel Morakniv uses in the Garberg and Bushcraft lines. Tough enough to baton and easy to bring back with a stone in the field, at the cost of rusting if neglected. The black coating on the blade is corrosion protection, not decoration.

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.
