Ceramic File
Ok! I give, I have looked and looked but no matter what I type in I get nothing that looks like what you had. The best I find is for Gunsmithing and they are every shape except flat (round,triangle,square) or too large meant for sharping knifes.
Why no link?
HELP!!!!!
Great to hear! Practise the different superstones before your tuner arrives to get a "feeling" for how they work. Personally i use 800 and 1200 grit. For larger cent calibration i use a triangular jewelers file (Cutting 3 - very fine) As Kinya shows in the #7 - switch to a superstone of 1200 when the cent value start getting close to "0". Using the superstones gives us totally control and possibility to deal with 0.xx cent intervals. Another thing - i do think that Kinya wrote a year back or so, how to file on the reed when we are dealing with 0.xx cent intervals. I do not remember when it was but convinced that Kinya can recall it.
