3x8 Sharpening Stones

The DMT Universal Stone Holder is built to lock your sharpening setup in place so you can focus on the edge, not chasing your stone across the table. Whether you're running diamond plates, water stones, or hybrid stones, this holder keeps everything planted and predictable.

The adjustable design allows it to fit a wide range of stone sizes, making it a versatile base for just about any sharpening setup. Once tightened down, it holds firm without flex, giving you consistent pressure and control through every stroke.

Rubber feet on the base grip the work surface and prevent movement, even during aggressive reprofiling. The frame itself is simple, durable, and built to take abuse without becoming a weak point in your system.

If you're serious about sharpening, this is one of those foundational pieces that makes everything else perform better.

The Hybrid Bond Diamond Sharpening Stone is built for those who demand precision, consistency, and long-term performance. Featuring true diamond abrasive set in an advanced hybrid bond, this stone delivers fast, controlled cutting with a refined scratch pattern across a wide range of steels.

The hybrid bond is a carefully engineered blend of resins and metallic components, designed to strike the perfect balance between cutting performance and durability. It behaves closer to a softer bond for improved polishing and feedback, while maintaining higher wear resistance than traditional resin-bond stones. The result is a stone that cuts efficiently, finishes clean, and holds up over time.

Diamond abrasives provide aggressive material removal and deep cutting ability, making this stone highly effective for everything from reprofiling to refining edges.

The larger 3" x 8" format offers increased surface area for improved stability, smoother stroke consistency, and greater efficiency, making it ideal for freehand sharpening and larger blades.

Whether you're working on everyday users or high-HRC powder steels, this stone delivers consistent, reliable performance.
