Thread: Coticule slurry.

I'm guessing that it's due to the differences in garnet size and density between individual coticules. Perhaps larger garnets fractured into smaller pieces show a more noticeable increase in cutting speed than smaller ones do. Here are photos of the surfaces of two of my coticules: a La Verte and a La Petite Blanche. The La Verte has much larger garnets and is a much slower and smoother hone than the latter. My guess is that slurry on the La Verte made with a diamond plate would in effect be more similar to slurry on the La Petite Blanche made normally. Perhaps when the garnets are smaller to begin with, the change in cutting speed when slurried with a diamond plate is less noticeable.

La Verte surface:




La Petite Blanche surface:

That sounds plausible. Thanks for the pictures I didn't know that the difference in garnets were that big.

There is. My honing drawer. Next meet up I can give you one if you'd like and your DE's back. Haven't used them in quite some time.

Relevant to the topic of using a diamond plate to raise slurry I have too noticed that the diamond plate makes the stone more aggressive. This is not disputed by anyone. My theory is that as the razor is progressed through the slurry stages of honing that the stone smooths to a pre-diamond roughed surface through the burnishing effect of rubbing the steel on the coticule and the slurry dulls enough to get you to the same end result as if you had raised the slurry with a small bout of coticule.

I've shaved with razors off diamond and natural slurry without any noticeable difference.

Some would say otherwise.
