I'm considering buying an 80 grit Norton SG grinding wheel form Craft Supplies. It is fairy expensive; am I being sedcued by the marketing literature, or will it really be the last wheel I'm likely to ever buy and put a smooth edge on my gouges forevermore? I invested in a Woodcut Tru-grind jig and that has been a remarkable improvement (over freehand sharpening. I suppose anything controlled would be better for the amateur).
Anybody have any experience with the SG grinding wheel? Thanks
