Question: Best bench stone for polishing hss gravers?

[aaronhlin]

Hello,

I was told that black Arkansas stone, ceramic bench stone, and ruby stone can all polish a hss graver. I would like to know among the three, which one produces the highest polish on a hss graver? The reason for asking is because I cannot afford a ceramic lap.

The highest polish would probably be the ruby stone, which will also work on carbide gravers. Ceramic stones are excellent as well, but I believe the ruby stone will produce a mirror polish that exceeds what ceramic can do.

If you have a power hone, then I would suggest getting a cast iron lap and diamond powder from GRS. It polishes both HSS and carbide gravers so brightly and perfectly you won't believe it.
