Amazing job, the blade looks like it has the perfect degree of curvature! The ring at the end of the handle is a bit weird though, in terms of design having the ring be multi-sided is cool, but in terms of practicality you want a perfect circle for spinning. Very nice job though!
It is the same style of knife. The karambit was originally used for agriculture work, for cutting roots. Then it was weaponized and now almost all war movies and games have one in it now. Probably because it is such a fierce looking weapon! It was inspired by large cat claws, centuries ago, so that is probably why people like it so much. One of my favorite looking blades!
