Can someone out there tell me how you tell if a file or rasp is sharp
or if its ready to be scrapped. Picked up a couple handfulls of files
and rasps at a garage sale and do not have enough experience to know
if they are sharp enough. Is there a way to look at the edges of the
grooves or something?
Thanks a bunch
Bob, those files can be sharpened. If you contact Steve Knight you can
probably find out from him where he sends his files to be resharpened. IIRC
he has NEW files sharpened before he uses them.
You might even want to look and buy a great hand plane from him... ;~)

as long as it is a good file it is. anymore I have them sharpened before I use
them. the difference is pretty amazing. it is about 75% cheeper to get them
resharpened. anymore new files are not sharp to begin with.

It used to be said that you could drip them in Nitric ACaid to sharpen
them. It actually eats off the rounded off corners. A file often can
be used on copper and non-ferrous when it can't be used on steel.
1) Only use one file on one type of material-NEVER switch types of
materials being filied with a file.
2) You can go from filing steel to copper/brass but not the reverse.
3) ALWAYS rub chalkboard chalk on a file before using it on aluminum,
brass, copper, tin, lead, etc.. It fills in the gullets and allows
you to take a card file and brush the chalk out and reuse it.
4) Never oil a file; it allows the steel to slide over the surface
instead of cutting it; once it has slid, it is ruined.
5) Chalk and file and oil it. Keeps it from rusting. Just use a
degreaser to clean it up BEFORE you try to use it.

So does a file card. Thats what its made for. The comon wisdom was is to not
use a wire brush as they are made with hardened steel. Of course, it
natuaraly fallowes that people would start saying that about a file card do
to their ignorance.
It is also a good way to get sharp flecks of metal in your eyes,
fine particulates in your lungs, or toxins into your bloodstream,
if you aren't careful.
I could hardly believe it when I read that the anthrax at the
Postal Sorting Centers went airborne because the workers used
compressed air to clean the machinery. That has been verboten,
for just that reason, for decades.
That's not to say Steve is not careful, just a few words of caution
