Polisher’s Choice aluminum oxide stone for finishing operations with fast material removal on Hapstone sharpeners.
Series
PC series stones are designed for finishing operations with fast removal and controlled sharpening performance.
Abrasive
The stones are made of aluminum oxide with strictly controlled grain and a special bond.
Use
PC 1200 grit is especially popular as a finishing stone and is often included in Boride stone bundles.
Boride stones
Boride sharpening stones are used for sharpening knives on Hapstone sharpeners. Boride offers a wide range of stones with different performance values and wear rates.
All Boride stones are 6 mm thick and mounted on high-quality aluminum blanks. This thickness offers a longer life cycle than standard 3 mm Edge Pro stones.
Lubricants
Boride stones can be used with water, soapy water, Boride Bori-Lube, or a water solution of dipropylene glycol.
WD-40, refined olive oil, and oleic acid are options for experienced users only.
Preparation
When using water, soak the stone for 1–2 minutes. When using oil, apply 1–2 drops to the surface and spread evenly.
If the stone absorbs the honing oil, use a larger amount of oil.
Maintenance
Boride stones may have saw strokes on the working surface, lacquer residues, or small chips at corners and edges no larger than 1 mm.
These minor marks are eliminated during stone preparation. Additional lapping can be performed with loose silicon carbide powder or a diamond lapping plate.
