Controlled enviroment? Where's the fun in that?

Scalpel or x-acto blades are in all our PSKs becuase they fit in the Altoids tin. That's different than what Burn is talking about. Everythink in a PSK is redundant to a redunandancy. I have x-acto blades in almost all my tins, becuase they really don't have any bulk or mass. But if I'm using one, it's becuase (a) the Ka-bar is missing, (b) the Leatherman is gone, (c) the Victorinox Climber I carry on my belt is someplace else, (d) the Micra and everything else on my keyring is out of reach, and (e) the Vic Camper I keep in my bigger tin is on it's own without me.
