Hapstone Start Diamond stones set

Hapstone Start Diamond sharpening stones are designed for use in manual sharpening systems, such as Hapstone, and are ideal for sharpening knives made from various types of steel. The sharpening block, Hapstone Start Diamonds, consists of a diamond plate with a working surface of 152x25 mm and a thickness of 1.6 mm, adhered to an aluminum blank measuring 160 mm by 4 mm, with beveled ends in a "swallowtail" style. The abrasive layer contains diamond abrasive evenly distributed throughout the volume with a high packing density and a very narrow range of sizes.

Thanks to the galvanic coating, the stones have a very high speed and aggressiveness in metal removal. They work significantly faster than many other diamonds, and the multilayer galvanization ensures their long service life, which is several times longer than that of cheaper alternatives.

There are 5 grit sizes in the set, from roughing to finishing:

• 100 JIS grit
• 220 JIS grit
• 400 JIS grit
• 800 JIS grit
• 1200 JIS grit

For additional processing, it is recommended to use silicon carbide stones from Hapstone: 1000/2500. At the pre-finishing stage, it is recommended to use the semi-synthetic stone Hapstone 4000. For finishing, Gunny Juice with grit sizes of 9, 6, 3, 1 micron can be used.

If the diamond surface of Hapstone becomes dirty or dull, the manufacturer recommends cleaning it with ethanol. If deeper cleaning or trimming is necessary, silicon carbide powder and glass or a nagura with a grit size of 240 can be used.
