It can be said that the best self-defense weapon is the one you have on you. And while there are plenty of people that might like to carry around a battle axe or samurai sword, the legality and impracticality therein are a bit murky at best. Most times, however, all you need is something small to scare and fend off any would-be attackers – like the CRKT Williams Tactical Key
Built to fit on your keyring and resemble any other key you carry with you every day, this 3Cr13 stainless steel and glass-reinforced nylon device is ergonomically designed to fit comfortably in your hand and mimic the functionality of a push knife. And the creator, James Williams, should know – as he’s a former Army officer and martial arts instructor. But it’s not just a weapon. In classic everyday carry fashion, CRKT also built-in some alternative functionality, namely a philips head driver tip. So whether you like being able to defend yourself or you just know you’re going to have to tighten a few screws, this $10 everyday carry tool will get the job done right.
