- Wanting an alternative to a Naniwa, Shapton or Chosera 1000 at a lower price.
- Preferring a stone with more give than the Hard and Extra Hard versions of the same grit.
Water

Progression Ideas

- Following Step (Higher Grit): Nubatama Ume #2000 Speckled, or the 2000 Platinum for more speed.

Notes
- Made in three hardnesses: Medium, Hard and Extra Hard. This is the Medium.
- Ken pointed most buyers here rather than the Extra Hard, unless they liked Shapton-level hardness.
- A separate Ume 1000 Black brick exists at 50mm — a different stone entirely.

Internal protective wrapping (plastic or paper) may show signs of handling, minor tears, or may occasionally be absent—this never affects the condition of the stone itself.
