Helpful hints: a picture is worth a thousand words. When absent, at least an idea of blade shape, lock, a best guess at pattern, country of origin, and what the grips are made of can narrow it down. At this point there are too many variables.
Titanium framelock kerambit or ivory handled lock back wharncliff are both possible, and the makers are usually quite different, too.
The lack of any blade markings is indicative of foreign make, and possibly not too expensive.
