A unique tribute to military history the Trench Bottle Opener is a great conversation-piece both for display and use. Crafted into the shape of half of a trench knife handle, it has two rings for your fingers and the bottle opener is integrated into one end. Opposite the bottle opener, on the other end, is a lanyard hole. It’s cast of one, solid piece of antique brass with “U.S. 1918” stamped into it and its dimensions are 3”x 2 3/4”. And if things get dicey where you’re at, the Trench Bottle Opener doesn't make too bad of a self-defense weapon in a pinch.
