Raise your hand if you loath adding and / or removing keys from your split keyring? The action usually requires you to jam your fingernail between the rings in order to lift one of the “tails” up far enough to add or remove the key. Broken nails and pinched fingertips are a common result. The Key Sergeant is a handy little tool that provides a wedge to easily split the metal ring without splitting your nails in the process. The Key Sergeant is available in 3 styles and several colors. It is priced from $1.29 – $3.59 each. You can even put it on your keyring… but I guess you’d need a second Key Sergeant to help you do that.
