One shape, two metals: the Dual Metal Bottle Opener Knuckle is offered in brass and in TC4 titanium, both carrying the classic bottle-opening knuckle outline at about 48 x 39.5mm. Pick the warm, dense brass or the light, rust-proof titanium.

Brass or Titanium, Your Call

The brass versions, stone washed or polished and brushed, bring the classic golden heft and a patina that improves with carry. The TC4 titanium versions, plain or polished, bring aerospace-grade strength at a fraction of the weight. Both share a 24mm finger hole and a 3.8mm rope hole, so either wears on a cord or a keychain.

A Knuckle That Opens Bottles

The integrated opener means the piece works at a barbecue as well as in a pocket, and the compact frame slips into a pouch or a coin pocket. Choose the metal that matches the rest of your kit.
