And of course there is always a tiny nail or two there to grunge up the end
of the knife on as well!

The glass in an external wooden window frame is cracked and needs
replacing.
The putty at the bottom of the frame is cracking and easy to remove but
the putty at the top and sides is rock solid. What is the best way to
remove hard set putty
without damaging the wooden frame?

Thanks

But IME it's a brutish implement, designed to butcher the frame. You could
use a Stanley knife to score a line where wood meets putty. Often the
putty will lift when the glass is removed.
