Keychain multitool
Reinventing the keychain

I’m tired of my keys always jangling in my pocket, so I built a key-multi-tool out of a Crank Brother’s M5 bicycle tool. While I had the tool disassembled, I rearranged it so that the M3, M4 and #2 phillips were on the same side, which leaves room for five keys on the other side. A quick grind with the Dremel and buff with a polishing wheel leaves the keys smooth and compact in my pocket. If you have more keys than will fit on the M5, you can either try to make longer axle pieces or start with a larger tool like the M10.
