tuning stability

[Newton Hunt]

Brass drifts are OK, but you can use them to the detriment of the tone
and bridge.  The use of an upright shank will show you if you are using
to much force by splitting or leaving indents on its end.  You do not
need a lot of force, just a light tap with a light tool, like a small
vise grips.

There are tools made for leveling and lifting coils that are made of
tool steel which they need to be.  A hammer shank is not a proper tool
for these applications.
