Have you ever wondered this:" what is the meaning of the number 1000 on a stone?", "are all the stones with the same number printed on the sufrace perform the same?".
Well, I did a sharpening comparison between two of the most highly regarded stones out there, the Naniwa Chosera 1000 and the Shapton Kuromaku (Professional) 1000, and also threw the Suehiro Cerax 1010, King Deluxe 1000 and even the Chosera 400 into the mix.
I am sure the result will surprise you!
