The single-sided Diafold sharpener offers a convenient, lightweight, and portable solution for sharpening knives, garden tools, and specialty equipment. It is available in four grits: extra coarse, coarse, fine, and extra fine. This sharpener features fold-and-go handles that protect the Diafold Diamond serrated knife sharpener when it's not in use, making it easy to carry. With DMT's monocrystalline diamond surface, it sharpens knives and tools more quickly than traditional sharpening stones.
