The kubaton looks like an ordinary keychain, but in fact it is an aluminum protection device. The keychain is great for jabbing, striking pressure points and eye gouging.  Measuring 5 inches in length, it’s long enough where you can use your keys as a weapon by snapping or side lashing them against an assailant without your hand enduring any injury.
