Review: Excellent stone for the money! - This stone is amazing for only 45 bucks. The reason it's so cheap is cause it's a lot thinner than other stones, at only 10mm thick, so it will not last as long. However, some users have reported that it warps after using, but I have not had this problem at all. I have sharpened about fifteen different knives on it and it's stayed flat and true this entire time. It is a splash and go and I let it dry with a fan after every use and have had no problems with it at all. From what I have read online, it is basically a rebadged Naniwa 12k super stone at a significantly lower cost. Some of the older stones have SS on the side in the serial number, which matches the super stone. The stone is very hard and stays very flat, which is excellent for sharpening my yanagis and usabas, which I need really sharp for work. However, it does load up fairly quickly, especially on single bevel knives so it has to be removed with either a rust eraser or flattened out with a flattening stone in order for it to actually cut again. Leaves an excellent mirror polish on my knives and could not be happier for the price.

### ⭐⭐⭐⭐⭐ Worth every single penny!
*by R***D on May 22, 2024*

I bought Shapton 16k prior of purchasing this stone. I should say that I am surprised by the quality and efficiency of it. Even the gritt is less than Shapton 16k but it works way better. 100% recommended! Buy it and you won’t regret it!
