The Sharpal® 169H Dual‑Grit Diamond Sharpening Stone is built for aggressive edge repair followed by controlled refinement on a single stone. Its 3" x 8" format provides enough length and width to handle a wide range of knives and woodworking tools while maintaining consistent contact during sharpening.

The extra-coarse 220-grit diamond surface removes heavy damage quickly, making it effective for restoring chipped or severely dulled edges. Flipping the stone reveals the 600-grit fine surface, which smooths scratch patterns and improves cutting performance without jumping straight to polishing grits. This progression supports faster recovery while keeping edge geometry under control.

MirrorFlat® technology holds the stone to a precision‑ground flatness of ±0.002 inch, helping ensure even abrasion across the edge and reducing the risk of rounding. The included Angle Pyramid® guide provides four reference angles, supporting repeatable sharpening results without guesswork. The stone is designed for dry use or with honing oil only. Water should not be used.
