Hi, I use a Viel belt grinder available from Lee Valley or Viel directly.
I have the plane iron/cisel attachment for mine, and I use a waterstone for final finishing.
If I was going to start over again I would use the Viel grinder and abrasive paper for the final finishing..........Regards, Rod.
P.S. I also have an 8" low speed grinder near the lathe for turning tools.
