Paul, thank you very much for expanding your already impressive line up of Japanese Water Stones. I sharpen daily by hand in a professional environment. The Naniwa Aotoshi, Green Brick of absolute Joy is a crucial component of my sharpening setup. If anyone is on the fence about purchasing this stone, jump off immediately and get it. It is the best 2,000 grit water stone I have ever used and many of my peers feel the same way. Thanks again Paul. I can't wait to try the new Naniwa Traditional 6,000 and 8,000, they are on my radar.
