That's a scary thought........my son-in-law-to-be works out in the woods, and HE wants a titanium wedding band. Oh well, he's got nine other digits........
Seriously, I hadn't heard that, and I can't imagine any kind of metal being so strong that NOTHING can get through it. Titanium is definitely more durable than the average metal, which would make it perfect for people who do a lot with their hands, ergo, my lumberjack son-in-law-to-be has made a good decision. I'll just have to caution him about jamming his ring finger.
