This stone offers a very generous work surface that would make working with long blades such as 300mm+ yanagiba easy. The lines are not toxic. The stone will self slurry with high pressure or polish more gently with light pressure. The stone has a full thin layer of kawa on the backside.
Uchigumori excel as polishing rather than sharpening stones. Although they will also leave very nice edges for kitchen knives, just more slowly than some other stones. This stone will leave a contrasty kasumi which hides scratches and leaves the surface of the bevel appearing wet. Uchigumori are at their best when paired with honyaki (especially tamahagane) or in applications where a matte finish is desired.
