Master Sugai’s favorite Fine Grain Sharpening Stone

This is Master Sugai’s favorite Fine Grain Sharpening Stone. He said this stone was one in a million. When he got this stone, it was cracked but once he started to use it, the feeling was different and better than others. According to our master, a cracked and worn out stone doesn’t mean it’s at the end of its life. This cracked and worn out stone is infinitely better than any fine stone Master Sugai has placed a knife on. He still uses the stone till this day.
