Need a good rough stone.

Mon Sep 24, 2012 7:37 pm

Hi,

I think I need to fill the gap between my Atoma 140 and my Shapton glass 1K.

Do you recommend the Atoma 400 or the Shapton glass 500 to do the job? By the way...are those numbers (grits) comparable?

Thank you for your help.

JH

Atoma 400 in this case. The 1k will get the atoma scratches out, and the 500 dishes faster than the 1k since it's a coarser stone.

Hi JH,

Yes the Shapton 500 would work really well as a tweener stone. It will save wear and tear on the 1K. The Atoma will work well too but it's a lot more money. As Mike says it won't dish and will last longer but I kind of prefer stones to plates.

The Shapton GS 500 will also provide better feedback. Sometimes I use it instead of the Atoma for small jobs, because it responds better.

I have to say, I don't love it. It cuts best with goodly amount of pressure and no mud/swarf, but sharpening this way encourages dishing. It's nothing to write home about(it's a Shapton, after all), but flattening it can be a bit annoying.
