I use an antique Revlon diamond file from the 1980s. They don’t make them anymore, understandably because they never wear out. Oh and I also use it to sharpen my cuticle nippers and tweezers. The plastic handle broke years ago but I replaced it with epoxied fiber.

I'm a machinist and you can get industrial diamond files for about $20-25 from a supply website called Mcmaster-Carr.... No ergonomic handle but they'll last forever if all you do is file nails instead of metal!
