I'm not sure I understand the advantage of having a safe edge for a
file (i.e. a smooth side with no teeth).

* * * * Let's say that you need a rectangular opening in an instrument
panel -- with sharp corners.

* * * * You can mill out the rectangle, but will wind up with rounded
corners, which man interfere with putting the instrument or control you
want into the hole.

* * * * The safe-edge files let you concentrate on squaring up one edge
at a time, without risk of the cut wandering too far into the other
edge.

to file the shoulder itself.

Ok, that makes sense. I've always managed those types of jobs with
regular files and trying to mind which side I needed to press on to
guide the cut. There are so many types of files that it seems like a
challenge just to learn the names, never mind learning what job each
is best suited for using.

If you find a reference or source for the sleeving you mentioned,
plese let us know. *I thought of making a roll up pouch to combine
some of the best of my files, but my sewing skills need more work.

Big Book.

The price is $0.89 for a 36" length. *Up to you to figure out which

convert the perimeter of each file at its largest to a diameter, and get
sleeving which will accept that diameter. *Maybe the next size up, in

Ok, I'll have to get some to try. Thanks.
