BOught it used, a while back @ flea market here @ Giants Stadium. Use it quite extensively and like it a lot, but was never able to buy/locate another one like this - McMaster or MSC.
The file is 4" long, .050 thick, .451 wide (probably .5 was the goal). It says, by the root of the file:
SWISS 2 and below number 2 it has "star, cross, star" pattern.
Clearly it is Swiss pattern number 2, single cut pattern, on all 4 sides.
It is rectangular all the way - does not taper off to a point.
No name of manufacturer on it, but right before "SWISS" it has 2 letters that read like "AN", but I am not as letters are worn off a bit.
Do you know where can I get me another one like this ? I have
20+ files, 90% Nicholson, American & Swiss patterns, that I work with (making accordion reeds and reed plates, dies for a press etc), and this one is really a godsend for some work. No other file I have, including needle variety, cuts it (NPI :).
