Diamond grinding stones with dual surfaces for versatile sharpening - Dual grinding surfaces: rough 400 gauge head for quick sharpening and fine 1000 gauge head for honing. No lubricant required, dry grinding. - Superior performance: diamond coating provides a very hard, fine, smooth grinding surface that improves restorability and sharpening results, helping edges recover like new. - Safe design: a large steel blade guard sits between the handle and the shank to protect hands during grinding. - Comfort and control: a large ergonomic handle offers secure, fatigue-free grip. A simple slide engages the fine diamond coating, enabling fast, consistent results at any angle and helping prevent blade damage. Key attributes - Function: two-sided diamond grinding for rough sharpening and fine honing with dry grinding. - Material: diamond-coated surfaces on a robust metal body with a steel blade guard. - Performance: fine, smooth diamond surface for precise sharpening and edge restoration. - Design: large ergonomic handle and hand protection guard for safer operation. Usage scenarios - Restoring edges on woodworking blades such as chisels and plane irons. Use the rough 400 gauge surface for rapid un-sharpened edges, then switch to the 1000 gauge surface for honing to a fine edge. - Re-sharpening general metal tools and edged implements in the shop. The dry grinding capability avoids lubrication requirements while delivering consistent results. - Quick maintenance of tool edges in a home or professional workshop. The guard and ergonomic handle support safe, controlled use across a range of angles.
