Does anyone else run into this difficulty?

Every couple of weeks I encounter a piano that loves my tuning hammer - that
is, the pins seem to grab the tip so that it does not slip off easily. The
extra motion to reach down and pull the tip loose wastes time and has to be
done gingerly so as not to disturb the pin setting.  It does not appear to be
associated with a tight fit, as there is usually a little wobble even so.
 Could it be the effect of wear over the past 40 years (Hale hammer and tip
from about 1955)?  Powdered teflon in the tip does no good.

Is it in the surface characteristics of my tips + the tuning pins?  Anyone
have a solution?
