About this item:

  • OTTO KEYES IMPACT TUNING HAMMER: The High Quality Impact Piano Tuning Lever with an 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: Comes with a #2 star tip that is designed to fit tuning pins with square heads. It will fit tuning pins on most pianos except for those with smaller than normal tuning pins (mostly found on very old, European pianos). The tip is removable so that you can switch it out with other size tips as needed.
  • SLIDING WEIGHT ADJUSTMENT: The Keyes Impact Tuning Lever has an eight position sliding weight on it. There are different places along the lever where the weight will lock. The further out you place your weight, you will have more force working with you to turn the lever. If you are working with very tight tuning pins, you will put the weight further out to help it be easier to turn, and vice versa.
  • PROVIDES PIVOT CONTROL: This tuning lever does not 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. This gives the tuning pin a jolt, allowing it to move in increments rather than a smooth pull like you would get with a normal or standard tuning hammer.
