The old ones used to use those for hammers, war clubs, whatever needed hitting was fair game for a hittin` type of tool... with the curved portion of the jaw joint sharpened, it seems it might`ve made a decent gut hook when used in "Battle-mode"... Mine has a leather wrap around the thinner end (over the teeth as well) for hand protection & a thong for going `round the wrist so as not to lose it while on horseback or when running across the battlefield... living history re-enacting can be fun if`n ya do it right,
