Per my earlier assessment, I agree with Jim and stick with my gut feeling that this is a hunting implement based on the markings and styling. As far as a "cheese knife" or fruit cutter, I would again point out the fullers/blood grooves on this piece (although some fruit can be quite juicy, I suppose!
The curious point could be decorative, but it seems to make total sense that it could be used to eviscerate game and gut fish as Jim pointed out. Going back to the talismanic symbolism, I always find it fascinating that even in european society, the properties of the "hunt" and magic to call up luck at finding the game combine nicely with these talismanic pieces.
