SW/parts question

[Richard Brekne]

The basic idea of more to less shank mass / stiffness is not unusual. 
Tho there are several different ways this has been accomplished through 
the years. Pretty common today is the use of so-called hex shanks... not 
so hex mind you.. but just so. These are often either 2 sizes or 3 
dependant on the piano. I like to use three for most situations. Doesnt 
cost any more and makes a smooth transition to the thin ones in the treble.
