I got a yellow coticule not too long ago. I thought I would give it a run and check it out. I cant get a good edge off of it. The edge seems to get only a tiny bit sharper from dull but smooth. But in comparison, the edge seems to be consistently sharper off of the norton 4k. I've tried the coticule with slurry to keen up the edge before polishing as well as water only after the 4/8k. The edge just seems to dull.

Yes, I am minding the pressure ha.

This is my first foray into the natural stones and I am thinking there is a different technique associated to the coticule than the 4/8k synthetic.

Any tips? Do I really have to do laps with slurry for 20 minutes to keen the edge? It seems like alot to me.
