SHOP CASE KNIVESRestore even the most damaged blades with the DMT Single-Sided Diafold Extra-Coarse Diamond Knife Sharpener—an essential tool for professionals and serious users who demand fast, aggressive sharpening performance. This rugged, compact sharpener is built around a 60-micron (220 mesh) monocrystalline diamond surface that makes quick work of nicks, chips, and dull edges. Whether you're in the workshop or out in the field, this tool gives you pro-level results without the bulk or hassle of traditional stones.
Designed for efficiency and durability, the Diafold Extra-Coarse sharpener eliminates the need for oils or messy lubricants. Its diamond abrasive works dry or with water, offering low-maintenance convenience with high-performance sharpening. With its fast-cutting capability, it removes metal quickly and evenly, reshaping damaged edges in minutes and outperforming oil stones in both speed and longevity.
Measuring 4 inches by 1 inch, the sharpening surface offers a generous working area while maintaining portability. The folding handles serve a dual purpose—extending to a full 9½ inches for sharpening, then folding down to just 5 inches to protect the diamond surface when not in use. This fold-and-go design makes the Diafold ideal for tool kits, backpacks, or glove compartments.
Engineered for heavy stock removal, this sharpener is perfect for restoring knives, axes, garden tools, and specialty blades. Its robust construction stands up to repeated use, whether you're a craftsman, mechanic, outdoorsman, or anyone who needs dependable sharpening in rugged environments. The monocrystalline diamond surface is more durable and efficient than conventional abrasives, staying flat and consistent for reliable edge maintenance over time.
To use, apply light, consistent strokes, and increase pressure only as needed. The diamond surface won't clog and requires just a quick wipe after use to stay in peak condition. Proudly made in the USA (with handles made in China), this sharpener lives up to the DMT name—trusted for quality and performance.
