How to use

1. Place the stone on a stable, non-slip surface. Secure your blade and identify the desired sharpening angle (most kitchen knives sharpen well around 15–20 degrees per side).
2. With light to moderate pressure, draw the blade across the stone from heel to tip in smooth, even strokes. Maintain the angle and repeat on the opposite edge as needed.
3. Check for a consistent edge along the entire blade. If nicks or heavy dullness persist, repeat the passes until the edge looks and feels sharp.
4. After sharpening, rinse the blade and stone, wipe dry, and store in a dry place.

Who is this best for? Home cooks who regularly maintain chef knives, outdoor enthusiasts needing reliable edge restoration for camping blades, and hobbyists or woodworkers who want a fast, effective initial sharpening step. If you’re rebuilding a dull edge or removing deep burrs, this 325 grit diamond stone is your fast track to a solid, serviceable edge. For a final polish, pair it with a finer-grit diamond stone to achieve a razor-smooth finish.
