Remember how the self defense experts used to tell you to place your keys between your fingers and punch? That's a good tip but a little more difficult than it sounds in a real confrontation. Now there is a sharp, polymer keychain knife that's much faster to deploy than using your car keys and far more effective for self defense!
Carry the
Heart Attack polymer self defense knife on your key chain and be ready to protect yourself anytime. The Heart Attack is small (3.5 inches long) and made of very tough composite polymers. Hold it between your fingers and punch. We have personally tested this little "push knife" to punch through sheets of corrugated industrial cardboard!
This keychain knife is not a toy!
