Pocket Knife Cufflinks ($57)

There are two accessories every guy needs: a pocket knife and a pair of cufflinks. So naturally combining those two items is a smart move. Knife Cufflinks are like classy concealed weapons that you can carry with you almost anywhere (with the exception of air travel of course). Each cufflink features a mini fold out blade that’s as sharp as you look when you wear french cuff shirts. Aside from looking damn cool, these little blades come in handy for cutting lose threads. The blades and handles are made from stainless steel and each set comes with a diamond dust sharpener.

Plasma Explosion Gun (concept)

It pulses with an invisible laser that super-heats the surrounding air, resulting in a plasma explosion that is strong enough to knock an intruder off their feet. And just in case the plasma explosion isn’t enough, electro magnetic waves cause temporary paralysis.

Knuckle Blaster Stun Gun

This uniquely-designed stun gun is meant for self-defense. It’s shaped like one of those brass knuckles, but it’s covered instead by a soft, rubber material to allow you to grip it more easily.
