After many years of use I finally ruined the first stone I ever had. This was the stone I learned to sharpen a knife on. After sharpening some knives an cleaning up I dropped the stone on the concrete floor an it broke into 3 chunks. So I used this stone for my carbon steel blades mainly. Some stainless AUS8 and some cheap kitchen knives. What stone should I get? I was thinking Norton Crystolon.
