Nope, well before they were marketing any type of impact lever. His =
class described a number of modifications he recommended to make to the =
Mahaffey-type impact lever (his opinion was that the Mahaffey-type was =
the best starting point). I seem to remember that some of the =
recommended changes included shortening the shaft length, decreasing the =
weight size, and adding padding - pretty much what his new levers look =
like.

  Gee, I wonder why Mitch would criticize that lever...?   Was this =
after Reyburn's Cyberhammer came out by any chance?

  Schaff sells exactly that - the Otto Keys impact lever (yes, they =
advertise it as a lever!). I remember that Mitch Keil (sp?) of =
Cybertuner fame offered significant criticism of that lever in his =
convention class on impact levers. I don't remember exactly what the =
criticism was though.

    Why not just design an impact hammer in which the weight can be =
moved up or down the shaft depending on the amount of force required for =
a particular piano or level of fine tuning.  Since you grip the hammer =
at the head it shouldn't matter.  Maybe someone has already, I haven't =
really looked at them all.
