Ice Cold Killer

Inspired by WWII contact naval mines, "Ice Cold Killer" is a stainless steel ice cube/whiskey stone with the shape of a naval mine.

Naval mines made a big difference during the Asymmetric Warfare. They are easy to deploy, inexpensive to manufacture, hard to remove, and can paralyze whole enemy fleet. Naval mine versus battleship is like David versus Goliath. By sinking numerous large battleships and advanced submarines, little things - naval mines - really made a big difference.
