an option for those of you that carry multiple key ring sets...I clip my keys and a couple of EDC items to an Uncle Mikes law enforcement duty belt type key holder, heavy duty nylon band, and nylon snap...I maintained the locked chemical storage, and flammables cabinet in my area of the building, and had keys for them on a separate ring for security, and the use of my colleagues...I added a split ring to the nylon band of the key holder, and simple carabiner to attach the extra keys... easy to remove and secure in my desk at night... my Maxpedition phone holster is attached with another of the Uncle Mikes bands, and provides an attachment point for a larger flashlight if needed
