Did you know there is a tool designed specifically for opening split rings? You know, the rings you use to hold your keys? I didn’t either till I read about it on one of my favorite sites: EDC Forums. The Xuron 496 Split Ring Plier will save you from pinched finger tips and broken nails. You just place the ring in the jaws of these pliers, close them and it will open the ring. Easy! This particular pair of pliers is $10.82 from Amazon. Amazon also carries other brands of the same type of tool that are less expensive. Check out this video that demonstrates how to use the pliers.
