Anyone have any experience with this?

A buddy showed me this. Seems pretty cool. There's a YouTube video of a guy killing a hog with it, but it didn't seem as effective as if you were in the water. Then again I don't think I'd want to be that up close and personal with something while diving. I know there are people on the site that dive, just wondering if anyone has a story involving this knife?
