The Tuning Pin tightener is death to pianos. No good piano tuner will 
use it. It destroys the pin block. It will hold for a while and will 
never hold tune after that. I had a tuner do that to an Antique piano of 
mine It Held tune for about a year. After that no luck at all. I gave it 
away to a Piano restorer who was going to build a new pin block.

The correct way to fix the problem is with shims. It takes a lot more time.

The pin tightener causes the wood to rot.

PS: if you want to tighten the handle soak it in water. It works for 
hammers and axes.
