picked up the Nitrous Stryker model yesterday and I love it. It is so intimidating to look at that i almost left the ccw at home. I mean this thing works like the action of a pump shotgun....just pull it out, flick the assisted opening and the sight and sound alone will scare off any perp!!!!! well maybe not, but it's still pretty sweet. I never thouight I'd spend that kinda money on a knife and now i will probably never go back to a lesser quality knife for carry
