I've been using the Norton Flattening Stone to keep my Norton 1000,4000, & 8000 flat, but it's not working very well. The hones are flat, but I've had to replace the flattening stone onvce already, and the groocves ont he second one are fading fast. Besides that, both were purchased new, and both of them had to be flattened before I could even use them. Norton needs to tighten it up with their flattenning stone.
I am really looking for a flattening stone in the $50-100 range that comes flat, and stays flat for a long time. If anyone has had this same problem, and found the solution, the I would really appreciate your advise. Thanks!
