So at the risk of starting another long debate about sharpening, I'm taking the plunge and buying a DMT extra coarse diamond sharpening stone. I've worn my Norton 220 grit waterstone to almost wafer thin and frankly am tired of the mess and maintenance of waterstones. I found myself spending more time lapping the darn things and cleaning up afterwards than actual sharpening and putting the sharpened tools to work. If I ever wear out my other three waterstones (likely only the 1000 grit) I'll replace them with the equivalent diamond stone.
