Notes from use — Harder than most uchigumori stones, but nothing about it feels like a hard stone: just a smooth, friendly slide. The slurry goes pitch black in very little time, and a short soak helps it along. Totally pure under the blade — no surprises anywhere on the face.
The shop is a sample of what I keep. If the finish you want isn't listed — a different size, a different character, something between two swatches — tell me your blade and your budget. There's no finish in this space I can't reach: I'll match it, or I'll make it.
