The Hapstone 4000 is a semi-natural sharpening stone that are used for finishing knives. Hapstone 4000 stones are unique. They are made of milled natural quartz with a particle size of 3 micron, delivering 4000 grit.
The Stones are 6 mm thick and are mounted on high-quality aluminium blanks.
Hapstone sharpening stones can create very uniform cutting edge without a pronounced scratch pattern. Breeze stones are universal and can be used to sharpen knives of any steel.
Hapstone 4000 is demanding to the pressure control during the sharpening. Apply as low pressure as you can to the cutting edge. If you achieve irregular scratch pattern or microchipping, it means the pressure was too high.
During the sharpening, the slurry is released from the Hapstone 4000 surface. You may keep slurry on the stone surface. The more slurry is released, the more abrasive the grinding compound becomes.
Hapstone 4000 stone is preliminarily lapped and does not require lapping after purchase.
All stones are 6 mm thick and are mounted on high-quality aluminium blanks.
Hapstone 4000 sharpening stones should be used with water or soapy water as a lubricant. Soak the stone in the water for 2 minutes before use.
