Was horsing around Sunday with my Great Pyr dog. He won, I lost. I mashed up my wedding ring finger. Didn't think much of it until I woke up in the middle of the night with it swollen and the ring quite stuck. Spent a couple of uncomfortable hours waiting for a jeweler to open to cut if off. No other tricks worked. Soooooo, I bought a ring cutter on ebay for $6 shipping included to add to my medkit. Also in SHTF will take and keep all jewelry off as a family SOP. A good slick little tool to keep around.
