We used to do the same sort of thing with xtals in the days when they
were expensive and hard to come by.

Except you didn't use a file. You used 600 grit silicon carbide paper
and a piece of glass for a flat surface.

Couldn't do that with my oldest crystal, it's in a valve glass envelope. 5kHz IIRC.

At the time, the "standard" crystal was the FT-243 which you could
take apart to get to the crystal slab inside.
