John bemoans a common saw sharpening problem:

May I suggest a quick application of layout fluid on the teeth prior
to the final pass?  The spray stuff is easily applied, and the
overspray is likewise easily removed when the pass is completed using
[drum roll, please] layout fluid remover.  Between start and finish,
it disappears from each tooth as it is filed.  If interrupted, you can
leave the saw for a month, year, or whatever, and pick up right where
you left off when you subsequently secure a round tuit.  Works a lot
better for me than candle soot, BTW.
