Not going there - that's for W&C, which I read before I replied.
Tactical gear, and in this case, it seems, with an EDC flavor, might go like : Small black space pen, Ti M-16 by CRKT, CMG Ultra - G (just got it and it throws like a AA Mini for 50% of the profile), Squirt P4.
In the field - space pen, Swamp Rat Camp Tramp, Victorinox pliers, Surefire G2, Glock 19C in a Fobus.
I asked for a definition of "tactical." Is it tactical to use the latter set of gear at the office?
