Designed and built to be the same size as a standard house key, the MSTR KEY Keychain Multi-Tool will take care of most of your EDC needs without having to carry or reach for anything other than your keys. What, exactly, can you use MSTR KEY for? Opening boxes and cutting tape. Prying open paint cans or pulling staples. Stripping wires and cutting line. Popping can tabs and bottle caps. Scratching lotto tickets. Tightening or loosening bicycle spokes. Splitting pills. There are also three different hex wrenches, a 1/4″ bit holder and four different screwdrivers. The safe to the touch tool weighs less than an ounce and is built out of 304 stainless that’s been electrochemically polished for corrosion and scratch resistance, along with a beautiful finish. This is one tiny multi-tool that’s going to last a lifetime.
