I use an old carpet stretcher very much like
this one:

to defrost my freezer. Works MUCH better than
the traditional tool (a kitchen knife).
Less chance of piercing the coils, and the
long handle means fewer scraped knuckles.

Jeez! They want UKP 65 for that thing!
Mine cost less than US$20, including
chipping from England.
