Oceanus Brass, a company that creates high-quality nautical tools, decided to machine a 20-pound tankard out of a bar of 304 stainless steel. They posted it on Kickstarter as a drinking mug, and wouldn't you know it, it's taken off.

"The Oceanus Brass Tankard is crafted on a state-of-the-art, Swiss-type, automatic lathe. Every component is given painstaking attention to detail. The Oceanus Brass Tankard's body begins life as a ~35 Pound cylinder of solid Stainless Steel. Through the precision of Swiss engineering fifteen pounds of metal are then carved off. Meticulous machining to a tolerance within one one-thousandth of an inch allows a 20-pound colossus marvel to emerge."

It holds 20 oz. While drinking from it is likely a challenge, one benefit is that it is childproof.

Killer detail: There's a bow shackle dovetailed into the handle.

They also offer a smaller "Featherweight" version that weighs just 8 pounds and holds 16 oz.

The Featherweight's going for $160, and the 20-pound Tankard goes for $350.
