Recurve blade

A Recurve blade has a concave (hollow) beginning of the edge which allows to better grip the material during a cut, geometrically this lengthens very slightly the length of the edge but it is more difficult to sharpen for someone who don't know. The tip usually ends in a spear or drop point.

Karambit spear-point

IIt's a knife that can be used as a combat knife thanks to its retention ring and as a utility knife thanks to its spear-point blade.
Another big advantage: it is much easier to sharpen than a traditional karambit.
