I need to buy some new files for handsaw sharpening and I'm
looking for recommendations. Nicholson used to be good but
I've heard that their stuff now made in mexico is sub par.
Grainger carries the Simonds brand. Any good?
I don't want any crap made in china or india .
Any others I should avoid and/or consider?

Specifics: All triangular taper files
6" slim, 6" X slim, 5" 2X slim (6" 2X slim would work too)
