I have a swiss army knife I keep in my jacket... but I keep it there all the time, no matter where I am. Hopefully I remember to take it out when I fly to the states this week.
I carry a knife in my backpack, but only for cutting apples and stuff. and sometimes to spread peanut butter on the lift. and for stabbing snowlerbladers
i carried a lil pocket (in ma pocket) knife from time to time. mostly in case i had to cut off my arm if a boulder rolled onto it... jea. and im not homosexual at all.
