Buy This Stone If You're

  • Reprofiling and thinning where a 220 is too slow but a 60 is more than the job needs.
  • Setting bevels on neglected knives before moving to a medium stone.
  • Wanting 50mm of coarse stone that will outlast heavy use.

Water

Nubatama range stones should not be permasoaked. Let dry fully before storage; coarse stones hold water a long time.

Progression Ideas

  • Preceding Step (Lower Grit): Nubatama Ume #120 or #60.
  • Following Step (Higher Grit): Nubatama Ume #220, or the Bamboo #150.

Notes

  • Ken listed the 180 and 120 as his choices when the 220 was not fast enough.
  • Green in the Ume range marks the coarse bricks — 180, 220 and 320 all shared it.

  • Stone: New and unused.
  • Packaging: While our inventory is new, the original packaging may show minor shelf wear, scuffing, or external softening due to warehouse storage and handling over the last five years. 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.
