Keep some tools handy at all times while adding a bit of macho military flair to your keychain with this Grenade Screwdriver Set ($6). Remove the cap, open the body, and inside you'll find a driver as well as small, medium, and large bits for both Phillips and flathead screws. Just don't forget to take this thing off your keychain before cruising through TSA.
Unless you're a real firefighter, you might not need all the utility of the Lansky Fireman's Battle Axe ($60) — but that doesn't mean it can't come in handy. Crafted from 1075 tool steel with an insulated, non-slip handle and leather sheath, this bright orange axe features an impact tool, a hose wrench, and a gas valve wrench. Oh, and it's load bearing up to 600 pounds, just incase you and a buddy need to stand on it. Or something.
We assume you won't be using it for nefarious purposes, but no matter what your intentions this Titanium Entry Card ($50) is a handy thing to have around. Made entirely out of aircraft grade titanium, it features two identical sets of lock picking tools embedded inside, ready to be snapped out and used. Just make sure you're using it for the right reasons — like breaking into the office over the weekend to toilet paper someone's cubicle. [Scouted by Joshua]
