Another thing on my wish list, an actual Grobet catalog...
American Swiss duplicated most, but not all of the patterns, but they didn't use the same numbers...
(The single digit , is, however, the cut of the file , from 00, to 6)
Two of them look like silversmith rifflers, 1 like a die sinker riffler, I have never seen the one with the loop at each end tho, and A.S. seems to have not copied it...
More or less concur on jewlers use, tho, cut's are usually 0-2 (4 is one step finer than 'super smooth')
