This is my boot/belt/pack strap (depending) knife.
It's a Carbon V Recon Tanto from Cold Steel (before their blades became either too expensive or too crappy).
I keep this on my key chain.
Because knives aren't allowed at school (even for staff).
And I have to take my Gerber "Gator" out & leave it in the truck when I get to school because.
I do have my Leatherman PST (retired model) on one of the straps of my booksack (and no one has ever noticed it).
And let's not get started on handguns.
