Yea i have one..
The guy at the swap shop showed me how to operate it, everyone does it a lil different actually. you can open the thing no frills, jus pop right open, or you could make it more fancy, which in tern is more intimidating.
eh i sometimes pack it...but the blade has long dulled..
and i've managed to cut my knuckes on two occasions...by opening it the wrong way (how stupid is that
)
They sure are fun though
