A string winding device for winding and unwinding the string on a peg of a stringed instrument has a generally cylindrical body with a slot extending inward from one end thereof. The slot has a plurality of sections, which are configured to engage different size and shape pegs on stringed instruments. The slot has a shallow and wide section, a deep and narrow section and a middle section of medium depth and width. A fourth section is located perpendicular to the other three sections and is configured for specialty tuning pegs. Extending from the top of the string winder body is a hexagonal shaft for engagement with a cordless screwdriver, drill or one of the hubs or cranks disclosed herein. A manual hub or crank with a handle may be used to turn the string winder body. The hub of the crank for the manual hub may utilize a flexible tab within the hub to interlock with a recess in the hexagonal shaft to hold the parts together during use. The crank has a lever arm attached to the hub and a handle attached to the opposite end of the lever arm. A user may hold the handle and rotate the lever arm clockwise or counter-clockwise in order to tighten or loose the string of the instrument. An alternate handle design also has a notch with an angled surface located in the upper perimeter of the handle. The notch is used for removing the string retainer peg or pin on acoustic guitars.
