About this item:

  • OTTO KEYES IMPACT TUNING HAMMER: The High Quality Impact Piano Tuning Lever with Adjustable Sliding Weight was developed by leading piano technician Otto Keyes. This hammer is designed to be used primarily on vertical pianos.
  • CHANGEABLE STAR TIP DESIGN: The #2 star tip that is included with this hammer is designed to fit tuning pins with square heads.  It will fit tuning pins on virtually all pianos except those with extremely small tuning pins. (Which is very rare).
  • SLIDING WEIGHT ADJUSTMENT: The other function of this keys impact tuning hammer is that it’s got an  eight position sliding weight on it, and it’s got a different spots that it can lock into so that the further out you have it the more weight, or more force that you’re going to have on that tuning pin. So, you’ve basically, if you’ve got tighter tuning pins you’re going to want that weight further out toward the end of the handle and if you’ve got looser tuning pins, in general you’re going to want to have it closer up, because otherwise your weight is going to be moving the pin to much if the tuning pins are real loose.
  • PRECISE AND ACCURATE MOVEMENT: Impact-style tuning allows for very precise, predictable actions, providing the user with precision and accuracy. A counterweight is attached to the far end of the handle of an impact tuning lever. The lever is turned in small increments with a flick of the wrist.
  • PROVIDES PIVOT CONTROL: It doesn't have a typical head, but it does have a portion that pivots, and you can rotate the star tip back and forth to give it more movement. And what it does is give the tuning pin a jolt, allowing it to move in increments rather than a smooth pull like you'd get with a normal tuning or even with a standard tuning hammer.
