Lubricants

• Soapy water
• Boride Bori-Lube

Stone preparation
Most sharpening stones require preparation, and Boride stones are no exception.
Additional lapping can be performed with loose silicon carbide powder or a diamond lapping plate to improve sharpening quality.
How to use
When using water, soak the stone for 1–2 minutes.
When using oil, apply 1–2 drops and spread evenly over the surface. If the stone absorbs the oil, use a larger amount.
Natural production marks
Boride stones may have saw strokes on the working surface, lacquer residues, or small chips at the corners and along the edges no larger than 1 mm.
These marks are usually removed during stone preparation.
