I decided to buy me the Robert Sorby Proedge Sharpening System. My grinder just doesn't do it for me. I can tell I'm just not getting my edges where I need them. I turn my pens and I can clearly see where I have a good edge and where there is a bad spot. As soon as I try to get rid of the bad spot, I create another one. Lol I've not really seen anything negative on the Sorby system and after watching the video (over and over again, Lol) on how to sharpen the different tools, it looks like the system that will fit my needs better. I probably won't see it for a week or so but I will surely give an update after the first attempt I make to sharpen.
