Hello gents. Ive come to some conclusions lately(well not really as I want to hear what you guys think first). I have quite a few stones that produce nice edges but meh! Not sharp enough. My cotis, and my kouzaki just don't get the keenness that Im looking for. Before I fire sale these, any other suggestions? My cotis Ive done heavy slurry, light slurry, water only and the edges produced are definitely shave ready but not what I like to shave with. Im spoiled from ,my suehiro 20k, the nakayama asagi mizu and ozuku asagi. These produce very keen edges and that's what I like to use. I got rid of my nortons and naniwa 12k recently. And why not thin the herd out some more being that I don't think I want to shave off these edges.ANyway you guys are great so any feedback is appreciated.
