Switchblade

A friend just gave me one of these as a gift. Pictured is a Colt M16K automatic blade, however mine is actually a Colt AR15K - originally produced as a manual blade but custom converted to a dual action automatic with the same sleeper button as pictured above. Apparently, my friend used to deal in knives and still has quite an assortment of blades - from stilettos, switchblades, and fixed blades, to a set of brass knuckles with a button activated razor sharp "gut-hook" that pops out the side when triggered. (pictured below - the opposite side is engraved with a FTW logo...very classy item)

I was previuosly unaware of such a contraption, but now understand how handy these knuckles are for performing the classic smash-n-slash move, often seen issued immediately preceeding a finishing heel-stomp-to-the-head. This combination has been perfected by many elite military and biker gang brawlers throughout the US and abroad.
