Two tools in one frame: the Knuckle Window Breaker Bottle Opener is a 3Cr13 steel knuckle duster with a hardened tip for emergency glass and an opener cut into the body for bottles. At 75 x 52 x 12mm and about 128g, it carries real weight in a compact shape.

Break Glass, Open Bottles

The protruding tip is sized to take a vehicle window when seconds matter, while the integrated opener means the knuckle earns its keep at a campsite or a picnic too. The 3Cr13 steel gives a dependable, rust-resistant body, and the titanium-tone surface keeps it smart.

A Solid, Balanced Frame

The finger holes follow the hand so the piece locks on, and the 128g weight gives it presence without being unwieldy. Keep it in the car, the kit bag or the drawer as a tool that does more than one job.
