The DMT Aligner Replacement 4in Diamond Whetstone Sharpener Extra Fine 1200 Grit Green is a precision diamond sharpening stone designed for professionals, enthusiasts, and hobbyists who demand a polished, razor-sharp edge. Part of Diamond Machining Technology’s (DMT) trusted Aligner™ interchangeable stone system, this extra-fine whetstone delivers fast, reliable edge refinement after initial sharpening with coarser stones. Whether you are maintaining kitchen knives, hunting blades, or woodworking tools, this replacement stone ensures your edges are smooth, sharp, and precise.
Measuring 4 inches in length, the DMT Aligner Extra Fine 1200 Grit Green stone fits perfectly in the DMT Aligner™ holder or other compatible guided sharpening systems, providing consistent contact with blades for uniform sharpening results. The green color identifies the stone as 1200-grit extra-fine, making it ideal for final polishing and honing. Its micronized monocrystalline diamond surface cuts steel faster than conventional whetstones while maintaining a flat, even surface over time. This ensures consistent, repeatable results that keep knives and tools performing at their best.
The extra-fine 1200-grit surface is perfect for achieving a smooth, polished edge on a variety of cutting tools. After initial shaping and coarse sharpening, this stone excels at refining and honing blades to a razor-sharp finish. It works efficiently on kitchen knives, hunting and outdoor knives, pocket knives, scissors, chisels, plane irons, and other precision tools. Using diamonds allows for faster sharpening with less effort, and the continuous flat surface prevents hollowing or uneven wear, common with traditional stones.
Lightweight at 3 ounces, this replacement whetstone is easy to handle yet stable when mounted in the Aligner holder for guided sharpening. Its compact size and durable diamond construction ensure precise, controlled results every time. The stone can be used dry or with water, eliminating the need for messy oils while simplifying cleanup.
