For sharpening the flat-topped carbide tips? I don't know, I don't have any flat-topped carbide cutters any more, haven't tried sharpening one. I have diamond plates from fairly coarse up to 1200 grit. When I sharpened the ceramic cutters for my llama shears I think I started with 600 then 1000 then 1200. The ceramic was so hard it took a much longer time than what the guy in the video said would work for the carbide.

I think the guy in the video said he recommended between 600 and 1000 grit for the carbide. I see he was using the Trend honing fluid. It's expensive but I always use it on my diamond plates.
