On Billy's new CD (video) he talks about an abrasive powder he puts on norton before honing. Has anyone discovered where to purchase this powder?

No he actually uses this compound and then immediately begins to hone. Says it provides more cutting power.Quote:

Oh, ok. Rottenstone is sorta like a Nagura, used for making slurry. I don't think it actually cuts, itself. Just makes the stone cut faster by making a slurry. Bill may be doing something different, but I think the Rottenstone is just for making a slurry. Rottenstone is often used by woodworkers for fine sanding on their projects and is, I believe, slightly more cost-effective than the artificial Nagura stones.

Rottenstone is decaying limestone. It is an abrasive. It can be used as an abrasive on a paddle strop. It is also extremely fine and breaks down with use to a smaller size. I have not tried using it for a slurry but why not try it?
Thanks folks.
