When I got married I thought I was a boss because I had custom titanium rings made for my wife and I as wedding bands. Not only did they look unique, but they kept with Buckminster Fuller’s idea of building the strongest things while using the least amount of material.

If I had known then about the Man Ring, I may have thought twice about that decision. Also made of titanium, Bruce Boone’s Man Ring boasts a bottle opener, straight blade, serrated blade, a saw for cutting plastic and wood, and a comb. They all retract and fold up neatly into the ring, and are sure to one day come in handy in some tight situtations.
