WASP Knives

[Plural of Mongoose]

A buddy of mine just mentioned these to me on the phone.
Anyone ever see or hear of these before?
Even though they are sold as hunting and tactical knives, Im not so sure the technology is really that applicable.
His reasoning as to why you need his knife instead of a handgun when out hunting or hiking is a little unsound, to say the least.
Interesting idea though.

yes theyve been used for awhile for hunting fish. The gas makes the fish float to the surface of the water.
