If you have a love of all things grenade, then check out this Grenade USB drive. It measures in at 60mm x 30mm x 30mm and weighs just 15grams. What it lacks in explosives, it makes up for with 4GB of storage space.

The Grenade USB drive is available in black, white, blue and orange and they look totally fake. Of course that doesn’t mean you can safely put them in your luggage and take them to the airport. They frown on all fake weapons.

Obviously you shouldn’t try this at home. It’s not a real smart idea to start modding live grenades. This one was an inert hand grenade, therefore the creator still walks among us. Ingredients? 1 inert grenade, a 1GB Sansa MP3 player and a hacksaw. That’s all you need.

If this sort of lethal DIY project interests you, you can try your hand at making one. Just don’t lose your hand…er…arm. Torso. It looks like a fairly simple build and a basic description can be found in the link below if you want to have a look. This is one of those Field of Dreams deals. You know, “If you build it, they will come”. They, being the FBI, local police, Homeland Security etc.

It takes a special kind of nerd guy to strap a hand grenade to their wrist. First off it’s bound to be heavy thanks to it’s stainless steel case contruction. Plus it’s bound to get you all kinds of weird looks as you flip it open to see the time.

Chuck Norris may be the only person in the world that this looks appropriate on. It’s even water-resistant up to 3ATM, which comes in handy when you are pretending to be a Navy Seal. Comes in Army Green or Matte Black finishes with either a skinny canvas or wide leather and canvas wristband. They start around $125 each.
