Carborundum Compass Brand 8" Dual-Grit Sharpening Stone – Professional Coarse/Fine Combination Whetstone (25x50x200mm)

The Carborundum Compass Brand Combination Sharpening Stone is a professional-grade abrasive tool designed for those who demand precision and longevity in their edge maintenance. At 200 mm (8 inches) in length, this stone provides an ample surface area, making it ideal for everything from standard kitchen cutlery to larger survival knives and workshop tools.

This dual-sided stone features a Silicon Carbide (Carborundum) construction, known for its extreme hardness and ability to cut through hardened steel quickly.

• Coarse Side: Engineered for aggressive stock removal. Use this side to repair chipped edges, remove rust, or re-profile a dull blade that has lost its primary bevel.

• Fine Side: Perfect for the secondary stage of sharpening. It refines the scratches left by the coarse side, smoothing the edge to a sharp, functional finish ready for daily use.

Whether you are a professional craftsman or a home enthusiast, the Compass Brand stone ensures your tools stay sharper for longer with a flatter, more consistent sharpening surface.

Optimized Usage Guide

• Pre-Soaking: For maximum efficiency, soak the stone in water or apply a high-quality honing oil for 5–10 minutes before use to ensure a smooth stroke and prevent "clogging" with metal filings.

• Stroke Technique: Use long, sweeping strokes across the full 200 mm length of the stone to ensure even wear on the abrasive surface and a consistent edge on the blade.

• Cleaning: Periodically scrub the stone with a stiff brush and soapy water to remove built-up "swarf" (metal particles), keeping the cutting surface aggressive and effective.
