The round file size has to be matched to the chain, that's
not something to upsize or downsize. It won't sharpen right,
and won't cut right with the wrong size.

The "depth gage" for the flat file is also not optional (for
me, anyway).

Glad you can find some Youtube videos. It's nearly
impossible to learn except to work with someone in person.

Interestingly, I knew it was dull because sparks were coming
out of the
tree limb I was cutting (but there was nothing but virgin
wood) and the
bottom half of the limb circle was burnt black.

I think the minimum I need, based on your recommendations,
is the 5/32"
(4mm) round file and a flat file.

I see some don't recommend the jig tool that goes with the
round file but
what about the jig tool that goes with the flat file?
