Edge geometry
Scandi, flat, convex — pick your grind.
Three grinds cover almost everything in the backcountry. The difference is how the steel meets the edge, and what that means for cutting versus abuse.
The grinds
scandi flat bevel, no secondary — easy to freehand flat full taper, slices clean, easier to chip convex rounded bevel, toughest, hardest to sharpen
Pick by use
Carvers love a scandi for control. Kitchen work wants a flat grind. If you baton firewood or dig with your knife, a convex edge survives what the others won't.
