Offset Screwdriver for rocker capstans


Special screwdriver for rocker capstans, often called “Bechstein offset screwdriver”.  This ingenious tool will preserve your sanity when working on rocker capstans and “tied actions” on vintage Steinway, Bechstein and other grand pianos and squares.  The four screwdriver blades on the front cube are oriented to fit the slot as you turn the screw and roll the tool handle to the next screwdriver blade.
