One of Howtomakeadollar's erstwhile contributors recently launched MensArmor.com which sells men's wedding bands that are bullet proof. In a video posted at mensarmor.com, the ring is hit with a big sledge hammer, driven over by a truck, used as a chain to tow a car, and blasted with a shotgun against a cement block. The ring stays in good shape throughout all the abuse.
If you are on the market for a new wedding band, give the thing a look. The ring is stainless steel, and made to look like a high grade nut or bolt head. The site already has several positive comments from people who have worn the ring. It is certainly a revolutionary design that I've never seen before. Go have a look!
