If a chess battle should ever erupt into all out war, this painstakingly crafted chainmail chess set can protect against slashing sword blows. The rings are super small, so it might even deflect an arrow or two.
Unfortunately, you can't just run out and pick one of these up in a store. But if you have some patience and the build info supplied by the craftsman behind the board, you might be able to put one of these together in about a year's time. Eh, I was never much into chess anyway. [CMB via CrimsonLinks via Make]
