A serious titanium knuckle with a job beyond looks: the Titanium Knuckle Window Breaker is a TC21 titanium four-finger frame with a hardened tip sized to take a vehicle window in an emergency. At 75 x 53 x 15mm and about 95g, it is a substantial, balanced piece.

Titanium You Can Rely On

TC21 is an aerospace-grade titanium alloy: strong, light and completely rust-proof, so this knuckle survives a damp pocket, a beach bag or a glovebox without a mark. The four finger holes follow the natural hand, and the window-breaking tip adds a genuine rescue function to the self-defence shape.

Wear It With the Chain

The No.2 option adds a titanium buckle and chain, so the knuckle becomes a worn piece rather than a pocket item. Whether plain or chained, it is a tool built to be carried and trusted.
