Conventional wisdom says bullets and booze don’t mix, but we beg to differ. In fact, Cool Material offers a .50 Caliber Bullet Bottle Opener ($20) that makes a great addition to your man cave’s bar. Cut out of a decommissioned US rifle cartridge (originally conceived as ammo for an anti-air weapon), you can pry open your favourite beer feeling like Rambo himself. And measuring in at a whopping 138 mm, it makes you wonder what firing one of these might feel like—but we’d rather just drink the beer.
