Sootch00 did a review of these on Youtube. It is similar to the NAA mini revolvers, comes in .22 mag with a 1/2" barrel. The innovative thing is that it folds into the handle, then opens like a switchblade knife. Last ditch - "get off me!" gun, but kinda interesting. soocth00 complains about poor accuracy at 7 yards, but, for real, I couldn't see using it for anything more than contact range. Still, it's an interesting video, if you're interested in oddball guns.
