The main advantage to using the non-Dremel (Large wheel with jig) type
of power sharpener (whether from Oregon or from HF) is that the jig
helps to even out tooth length - which helps things to cut straight when
you've munged 3-4 teeth on one side by clipping a rock or nail. It's
what the pro saw shop here uses to sharpen chains.

There's a neat outfit I've been using for years with a file to answer that
problem. I still hate to take all the others down to compensate, but it's
the right thing to do.
