While the name is a little...uh, overt, the concept behind "The Man Ring" is pretty much brilliant: a more-or-less traditional metal band witha built-in selection of essential tools. The aerospace-grade titanium ring has a slightly squared corners, which house brass rivets and a hinge to support a bottle opener, a straight knife blade, a serrated knife, a saw for cutting plastic and wood, and a tiny comb, perfect for grooming your beard.
Each ring is built by hand by Georgia-based artistan Bruce Boone, and can be customized to your finger size. At $385, it's an investment, but this a is "a finely engineered and crafted piece of functional art" that could easily work as a wedding band. I'm just hoping it's comfortable to wear.
