Q: Does this stone need to be flattened?
Like other sharpening stones, it can develop a dish shape with heavy use. A Shapton lapping plate or lapping disc, available separately, keeps the surface flat and true.
220x moss Ha-No-Kuromaku stone used with the Veritas side-clamping honing guide


Ha-No-Kuromaku stones are the workhorses of many woodshops. Precisely graded sharpening media are bonded to create a stone that is durable yet fast cutting.
The moss 220x stone is a medium-coarse shaping stone for rapid material removal in reshaping a bevel or repairing damage to the blade. It’s one of three shaping stones with a range code of 1 (along with white 120x and blue-black 320x); the larger the blade to be shaped, the coarser the stone you should choose.
It measures 210mm × 70mm × 15mm (8 1/4" × 2 3/4" × 5/8") and is supplied in a color-matched live-hinge plastic storage case that also serves as a stand. Four urethane feet on the vented case bottom give a good grip, while molded ribs on the case lid hold the stone in place. Both sides of the stone are usable.
The stone can be used with the Shapton stone holder, field holder and pond. It can also be used as an oil stone, but then must continue to be used with oil only. Weighs just shy of 20 oz (550g).
