they could have had a few of them as javelins, and intended them to stick in whatever they hit so they could not be removed and thrown back, the lower reversed barbs would keep it from being pushed all the way thru for removal, while the main barbs would be a bit nasty going either way. as stated, can't see them being a practical main weapon with them barbs.....
they must be fun to dust & keep oiled.........
