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 blue 1500x stone is a coarse honing stone (range code 3A) ideal for perfecting the bevel and is an excellent choice following a fine shaping stone.
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).
