Pitch Raising

Yes, David - slightly de-tune before putting on the tension. It breaks any
bonding that has occurred since the last tuning. I have contemplated one of
those impact hammers, but still use the Steinway extending one with many,
many different heads. My longest head is about the same as a 'T' hammer
shank in length. Very useful on  grands if the pins are too tight for the
'T' hammer. The long shank enables the handle to be positioned over the
keyboard.  In pitch raising I always use my "Quadrant" method so as to keep
equal tension across the plate.

I do tap the pitch down before coming up during a pitch raise and that
probably helps.  I'd be interested hearing from others who use the impact
hammer and if they have noticed the same thing.   Always looking new
tools...although I'd hate to have to carry 2 tuning hammers with me.

One thing that will help curb string breakage, IMO, is the use of an Impact
Tuning Hammer. It's SOP for me. Of course, this applies to Uprights only. I
tried same on a Grand once.....Yikes! Not a happy experience.
