Glad you chimed in, Sal! Thanks for the reply. I'll experiment with roughing up the corners of the old medium stones. I will say that despite feeling a little worn, those old sharpmaker rods still put a fantastic edge on knives. I feel the new ones work faster though.sal wrote: ↑Tue Jul 07, 2020 8:30 pmHi Vivi,
Good to hear from you.
We can make the corner of the gray/brown stones coarser when new by breaking the surface on the corners and they will cut faster up to a point where the corner is too wide and their coarseness diminishes and it's time to replace them. White stones really don't ever wear much but they will get finer of many many sharpenings. There is really no way to make them coarser. Sorry.

I've been experimenting with different abrasives. I ordered some 80-600 grit triangle stones from Congress. It's been fun but nothing puts a better edge on my SE knives than the sharpmaker rods. I do like the 120 grit norton crystalon rod for my SE beaters though, they give an extremely toothy, aggressive edge that'll rip apart anything.
