This is a handy bicycle 7 piece multi-tool in a hand made leather holster that my Dad made.
The holster has a belt loop on the back the extends around to the front up through a nifty shiny nickel closer hardware. The tool is designed by Iron and Glory out of Brooklyn, NY. It has 2mm through 6mm hex keys, along with both a flathead and a Phillips head screwdriver.
The overall dimensions of the case when closed are 3 3/4" tall x 1 5/8" wide x 1 1/2" deep.
Most would probably want it on their belt during their bike commute, in the console of the car, or maybe in the kitchen drawer.
