Just tried this paste and I think it seems to work well. Sharpened the knife about 2 weeks ago with 3000, 5000, 8000, 10000, and finished on 13000 grit stone, then did 30 rounds on canvas and 100 rounds on leather, and the knife was very good. After 4 shaves it unfortunately loses a bit and needs maintenance with some sharpening paste. I have used Giesen and Forsthoff's paste before and it worked of course, but I think this paste is slightly better. I felt the knife was as good as when it was newly sharpened. I have applied this paste to one side of the canvas cloth and it turned out great. I looked a bit on Thiers Issard's site and read about this paste and it is supposed to be at 1.6 microns, which corresponds to a bit over 13000 grits.
