If you tune pianos in the standing position, this key striker can significantly reduce or eliminate hand strain and back pain. Developed and tested over 5 years, this tool has been meticulously designed to achieve what others have not. A narrow shaft and grippy tip provide unmatched accuracy and significantly reduced slippage. The attached strap is intended to be adjusted to fit tightly enough that no grip strength is needed to keep the tool in the palm of your hand. The ergonomic handle fits comfortably in the palm of your hand with your fingers positioned to accurately manipulate the tool. As a result, this tool can significantly reduce hand, wrist, and forearm strain and fatigue. The length of the tool is intended to make it possible to reach the keys without bending over, resulting in less back and shoulder strain and fatigue.

This tool is extremely lightweight (only 99 grams for the largest size) but very strong and rigid due to an internal carbon fiber shaft that extends the length of the tool. The handle is made of textured matte PLA (polylactic acid thermoplastic) and the outer shaft is made of ABS.
