General Mfg. Wilson Keyring
If you're simply looking for something elegant to hold your myriad keys, the General Mfg. Wilson Keyring ($10) is well worth a shot. Formed from a single piece of 1/8" brass wire, each ring measures a pocketable 2" x 1.125", can hold a completely unpocketable number of keys, and features a small enamel marking in one of three colors — red, blue, or grey — to help you easily identify which set you're grabbing (should you happen to own more than one).
