## Description

Naniwa Chosera Water Whetstone SS-400 - Grit 400 Do you have high-quality Japanese chef's knives and do not want to compromise when choosing your whetstone? Only the best is good enough for you? Then the particularly fine Naniwa Chosera whetstone is the right choice. The Chosera is the masterpiece of Naniwa, it is intended for the professional who places the highest demands on fine and gentle grinding. Whether coarse grinding, fine grinding or the finest polish, the Chosera is the absolute high-end product among the water grinding stones: even the hardest steels can be wonderfully sharpened with the Naniwa Chosera whetstone. Especially practical: the whetstone comes with a small Toishi for straightening the grinding surface.

Review: Outstanding coarse stone for serious sharpeners - I’ve worked in the food industry for several years and have spent a long time studying and experimenting with knife sharpening. From my experience, achieving a truly sharp and durable edge comes down to three things: good steel, high-quality stones, and proper technique. The Naniwa Chosera #400 really impressed me. It offers strong abrasive power with a perfect balance of hardness. The tactile feel is smooth and consistent — it cuts quickly without wearing down too fast or clogging with metal. There’s no need for a Nagura stone, which is a big plus. For bevel setting or repairing damaged edges, this is the best coarse stone I’ve used. You won’t need to look for alternatives. For flattening, I use 3M metal sandpaper (grit 120) on a flat ceramic or marble surface. It works surprisingly well and is easier to manage than diamond plates or large flatteners. One useful tip: I recommend removing the Chosera from its plastic base. When left attached, it doesn’t dry evenly and can develop cracks over time. The #400 absorbs quite a bit of water compared to finer stones, so even drying is important. To detach it safely, use three wedges of soft wood — never metal tools, as they can chip the stone. Overall, the Naniwa Chosera #400 is an exceptional coarse stone that performs exactly as a professional would expect. Highly recommended for anyone serious about sharpening.
Review: The best stone for knives ever made. - The best stone for knives ever made. It's the best value, I would get an 800 grit too but yeah, you can't beat the value or the quality. You can spend more money sure but the grind patterns will marginally improve. The grind pattern is confirmed under a microscope. Back to this westons For the wet stone, please use this with a metal over the sink holder. This way you can run water over the wet stone which helps keep it clean, gunk-free and you avoid the long soak times. Remember to get a leveling stone, A cheap one will do, $15 bucks. If you need to know more just leave a review asking for help or a guide and i will answer your questions. This is the best brand. Also learning to hit the same angle ever time is the most important factor of all. It's hard and takes practice but there are good guides you can use and youtube videos to help with that. But yeah Again this is the best brand in the world. You can look at the grind patterns on the knives under an electron microscope to confirm how good this brand is. Scientist have done this and the grind is amazing some of the best out there. This rivals $400 stones! I would not use this to Sharpen steals like S90V, Use diamond plates for that and don't press down too hard on the diamond, you will dislodge diamonds.
