Hardness: 8.5~9/10
Fineness: 9/10
Cutting Strength: 2/3

Very fine, even, smooth, and light in colour. No lines or "Su". Ideal stone. Larger size stone with this quality would be over $1,000. Well suited for knife polishing. Better if used with Nagura or Atoma to raise the slurry first.

Good stone to experience the magic of Nakayama Suita Stone without spending as much.
