The DMT 11.5-in. Dia-Sharp® Bench Stone Coarse is a professional sharpening tool built for users who demand reliable performance, precision, and long-lasting durability. Designed with DMT's advanced diamond sharpening technology, this rugged bench stone provides the cutting power needed to quickly restore dull or neglected edges while maintaining the consistent sharpening results that professionals rely on. Whether you're maintaining kitchen knives, outdoor blades, woodworking tools, or specialty equipment, this American-made diamond sharpener delivers dependable performance for a wide range of applications.
The extended 11.5-inch sharpening surface offers a generous working area designed for long, smooth sharpening strokes. This increased length helps improve control and consistency, making it easier to maintain proper edge angles while working across the full length of a blade. The Dia-Sharp® Bench Stone is also ideal for sharpening tools with small contact areas and pointed edges, giving users the precision needed for detailed sharpening tasks while still providing plenty of surface area for larger knives and equipment.
The coarse 45 micron (325 mesh) diamond surface is engineered to quickly restore dull, worn edges and bring neglected blades back to working condition. This versatile grit strikes an excellent balance between efficient material removal and controlled sharpening, making it an ideal choice for repairing tired edges, establishing a fresh bevel, and preparing blades for additional refinement with finer abrasives. From everyday carry knives and hunting blades to chef's knives, chisels, and shop tools, this coarse diamond surface provides the aggressive performance needed to get the job done efficiently.
Unlike conventional sharpening stones that can wear unevenly, hollow, or develop grooves over time, the Dia-Sharp® Bench Stone is guaranteed not to hollow or groove. Its continuous diamond surface is precisely engineered to remain flat while delivering consistent, even sharpening with every use. DMT's micronized monocrystalline diamond technology sharpens faster than traditional stones, allowing you to restore edges quickly while reducing the maintenance often required with other sharpening methods.
Designed for convenience and stability, this bench stone includes non-skid rubber feet that help keep it securely in place during sharpening. The coarse grit designation is clearly marked on the side of the stone, allowing for quick identification when organizing multiple sharpening tools or building a complete sharpening system. No messy oils are needed, either. The stone can be used dry for simple sharpening or with water for easy cleanup after use.
Proudly made in the USA, the DMT 11.5-in. Dia-Sharp® Bench Stone Coarse represents the quality, innovation, and durability that have made DMT a trusted name among professionals. Woodworkers, chefs, craftsmen, and outdoor enthusiasts rely on DMT sharpening products to keep their tools performing at their best, and this coarse diamond bench stone provides the speed, consistency, and rugged reliability needed for serious edge maintenance.
