The “Bone Breaker” is a bottle opener keychain designed as an everyday carry tool for modern American’s living in today’s environment of political climate change. As gun free zones and weapon restricted areas continue to expand it becomes increasingly difficult for law abiding citizens to defend themselves. We designed the Bone Breaker as an EDC (Every Day Carry) tool that is not only unassuming and low profile, but can be legally carried anywhere one can carry their keys. Many previous customers have even brought their Bone Breakers through TSA security, making this the most effective self defense tool ever designed or produced that one can carry on a commercial airline! The Bone Breaker is legal because it is primarily a bottle opener keychain (be sure to specify that if questioned by authorities). Anything can be used as a weapon, some things just fit the hand better than others!
