Chuck in E. TN:
It has been over 45 years since I had any shop training, and I honestly can’t remember if my question was covered in class!
I want to know how to best remove the burr created by milling or turning, such that I don’t remove the crisp edge just created by the machine operation. This is especially difficult for me on small pieces as in model engines.
I use a fine file, but usually end up with a rounded, uneven edge.  I’m not sure if my choice of file, or my filing ability is in question. I have seen the deburring tools with the swiveling s-shaped blades. Is this what I need?
I have downloaded several old shop text books, but so far haven’t found anything on deburring. The only thing I have seen, is on this Japanese site: http://www.nmri.go.jp/eng/khirata/metalwork/basic/bari/index_e.html
He shows examples of burrs on small aluminum blocks that have been milled, and using the vertical edge of a wood bench to guide deburring the block. Are there any other secrets out there? I know this must be a fairly simple process. Maybe I’m over simplifying it? A Google search of “manual deburring techniques” hasn’t found much.

i use solid scotchbrite wheels for most of my deburring.

to leave a sharpe edge, i'd try scotchbrite sheets with a file/rule behind?

I watched a documentary on California's San Quentin prison and they showed the "museum" where they display items confiscated from the inmates.  They had three "shivs" that looked just like that.

I guess, with all the time on their hands, they do a lot of deburring there.
