The two longer ones are about 45" in length and I think are probably fishing spears...they each have drilled holes in them probably for a recovery string. The short one is about 23" in length.and is pointed both ends... totally made of hardwood. The two longer spears have hardwood tips with bamboo extensions. Likely to be from Papua New Guinea. Skillfully made and I'd say all are genuine used spears rather than souvenir pieces.
