I don't know much about files, but these "sideways" ones are supposedly special.

Nice, I'll have to check those out. I have the Tsubosan hardness testing files. The files in the video look like they have a cut angle similar to long angle lathe files. But lathe files usually only come in 10" & longer. Would be nice to have some smaller ones.
EDIT: Just looked them up. Says they are use for softer materials, for metal says only light metals, no iron. I don't like the sound of that as I mainly work with metal. I'm not sure if I want to order a set now.
