Made from the spent shell of a real 50 caliber bullet, the casing is now harmless but still packs a punch! The Caliber Corkscrew is hidden within the body of the bullet. Unscrew the bottom to expose the worm screw. Now you can really put a dent in any corked bottle that stands in your way! Easy to use and the compact design makes it externally functional for your bar. RSR - SABHCNBCF02
