Recently i added a coticule to my other hones. It is of greenish color and seems to be a good polisher. I was able to get a smooth shave with a blade that had to be touched up. I used a small coti of chamois color to raise slurry and applied the dilucot method followed by crox.
Today I tried to use the stone on a blade that i want to restore. The edge is blunt after sanding it. I spent 1 hour on the hone but i could not get it to shave arm hair.
Do you use a coti for restoration work?
