The Chosera stones are markedly harder than the Super Stones. Naniwa designed these stones for professionals who put the highest daily demands on their knives. Overall, these stones are best for those who don't have a lot of time to spend and need to quickly and cleanly sharpen their knives. Every Chosera sharpening stone is delivered with a special Nagura stone (67 x 49 x 25 mm) to put a fine sharpening paste on the surface of the Chosera stones during use. This 400 grit is excellent for establishing a new bevel angle or removing chips from the blade. Naniwa claims these are splash-and-go stones, but users say that soaking for 15 minutes really brings out the best qualities of the sharpening matrix. These stones measure 210mm x 70mm x 25mm.
As a woodworker,I’m looking for fast,effective ways to flatten blade backs and bevels. The Chosera 400 is truly a fabulous stone. It’s very dish resistant,loads up but still continues to reestablish edges and sharpen without glazing. The Nagura included with it is highly helpful in creating a cutting slurry.
This stone is not messy,produces a matte finish,and enables a 1000 grit stone to clean up the grind marks quite easily. If you’re looking for fast working,long lasting,and a lot less messy stone,the Chosera 400 is the stone to get. I’m amazed no one else has commented. This stone ROCKS!

Fantastic stone stone at a great price. Put a beautiful new edge on my Chroma knives that have taken a year and a half of heavy use without going over a low grit stone. This stone worked beautifully and I’m very glad to now have it in my maintenance line-up to give an older edge new life! Thank you Mark!
Chosera #400 is a hard and very dish resistant stone. It takes a little time to form slurry,but then it glides on yanagi’s blade. You may first try this stone for setting bevels/minor repairs on yanagis before going to a rougher stone. I prefer this over Beston #500 on yanagi,because Beston frequently needs water and its abbrasives get cought up in front on shinogi line and scratches the flat part of yanagi.On deba knife,this stone feels a little rougher,because of deba’s thick and narrow blade characteristics. For deba,I would prefer either Naniwa #150 or Beston #220,which Mark added lately. On the other hand,I would prefer it over Beston #500 on deba,as well. On double bevel knives,I don’t like it much because the narrow blade road skids on the stone rather than bite into it. At the end,if you have space for another stone,buy it for single bevel knives to use it for light bevel setting/minor repair work or as intermediary stone between very rough and medium grit stones. Good stone.
This stone is a beast. When I first got it,I set bevels and removed chips on over two dozen blades (mostly friends’ neglected knives) before I began to notice the dishing. Very hard,cuts fast,dishes slowly. Excellent coarse grit stone,and feels smoother than 400 when you work with it.
