Shapton Glass Stone Scratch Marks

This is a rough comparison of the scratches made by the Shapton Glass stones (white and gray). The process was the same as the with the Professional stones, I sharpened by hand using a single Jende Reed Knife for the entire shoot, working up from the white #120 to the 30K in order. I then went back from the 30K to the 4K, 6K and 8K  Gray stones, or High Carbon (HC) stones, labeled here as the JP stones (see this post that addresses the Shapton nomenclature). The Jende Reed Knife is a Medium Carbon Steel RC 60-61, and the steel type is from the Japanese standard SK series. I do not know the equivalent US Standard. It should be noted that results will differ on different metals.

The idea behind these pictures was not to produce high magnification shots of the edge, but more of an normal look at the results. The pictures were taken in the “worst” light so as to really see the surface of the bevel. You’ll notice just how “smooth” and polished the bevels come out in the 2K to 10K range, then how the scratches reappear at the 16K and 30K level.

Scratches from the Shapton Professional Shapton stones are here.
