Description
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 melon 8000x stone is an excellent finishing stone for polishing the micro-bevel sufficient for many fine woodworking applications. The 8000x is also recommended for preparation of the edge before final polishing on the purple 30000x stone to achieve a true razor’s edge.
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).
