Buy a better filter wrench.

Agree, whether or not that ultimately solves the problem. In a torque
war between the fliter wrench and the lightweight body of most oil
filters, it's the oil filter that should become damaged or distorted-
not the filter wrench.

Anybody ever use a pair of tin snips to cut the body of the filter
away and then strike an angular blow with a chisel or large
screwdriver placed on the remaining disc of the filter body near the
fitting threads?
Whatever the other considerations, it will be important to get that
filter off without damaging the threads and that normally calls for
unwinding rtaher than stripping it away.

I have used a dull chisel at the top edge of the filter to "drive" it
loose. It is usually difficult to get enough work space to do this on
a boat though. Sometimes a long screwdriver can be used instead of a
chisel. Most of times I have tried driving a screwdriver through the
filter the results has been that it simply twisted the can off without
removing the base.
