Hi folks,

I am looking for a flat screwdriver with an exceptionally thin blade,
for use on clock mechanisms. The blade needs to be at least 3/16" long,
but no more than 25/1000" thick. Does anyone know of a source for such a
screwdriver? UK sources are preferred, if anyone knows of them.

I know I can try grinding my own, but I'm not convinced I can do it neatly.

I have made a "fairly" thin screwdriver for old fashioned
saw nuts (don't ask).

I did it by hollow grinding on a small grind stone
mounted in a fixed drill.

Quite easy to do freehand, since the flat of the screw driver
is self registering.

e.g. one of the cylindrical ones here
