With having my BS back in service finally, was using it yesterday, and the blade was drifting (drift is a whole nother meeting).
YouTube had a video, I can't recall the fellow who had the jig, but I copied it:

The above Dremel has a standard 'Metal Cutting' wheel at the lowest possible speed, and trued to the face of the tooth as close as eyeball possible.
It takes just a second to take off a little of the back bevel of the tooth. No discernible heat.
After measuring several teeth/blade front to back, the results were surprisingly consistent @ 0.005" taken off.
Then, the actual bevel/gullet:

A 16d nail was with some PSA 400 grit SC paper was perfect for some finger powered honing (rotation CCW as pictured)
The teeth were surprisingly very sharp following this 40 minute procedure.
And, easier cutting w no drift.
(Honorable mention should be given to the value of periodic cleaning of resin and dust toward keeping the teeth cool and clean.)
