DMT (Diamond Machining Technology) has been at the forefront of diamond sharpening innovation since 1976, producing USA-made diamond sharpeners that deliver the fastest and most consistent sharpening results.

Unlike traditional sharpening stones, DMT sharpeners use industrial-grade monocrystalline diamonds, ensuring faster sharpening and long-lasting durability. DMT stones are guaranteed flat, and will remain flat throughout the lifespan of the stone. DMT also has diamond abrasive surfaces in a variety of shapes, perfect for specialized tools like serrated knives, gouges, and chainsaws.

Whether you’re maintaining kitchen knives, woodworking tools, or outdoor blades, DMT diamond stones offer a durable, high-performance solution trusted by professionals and enthusiasts worldwide.
