wasp knife

I believe the knife is mainly used for under water, would be expensive to blast some air in to a hog and i doubt it will do anything more than when just sticking it, might piss him off more

under water, when i lived in florida, i shot alot of large grouper with the speargun, it would have come in handy there for floating them to the surface, but even then, if i didn't get a spine shot with the speargun, I was generally going for a ride....

now where it may work, stick it in behind the hogs ear, take out its nervous system with a blast
