This tool is perfectly portable and beautifully practical. Tighten pivot screws, adjust pad heights and reseat wire springs, whenever you need to, wherever you are. This is a screwdriver and a spring hook all in one with protective covers on either end. The precision steel tools are housed in a case made of aluminium with a knurled centre joint for better grip and in one of four great colours. A lanyard on one end allows this tool to be attached to any number of locations: a loop on a bag, your instrument case handle, your keychain, anything that you can loop it around.
