With a blend of monocrystalline and polycrystalline diamond particles, these hones offer an excellent combination of cutting speed and durability. The monocrystalline particles cut aggressively but round over time through wear, eventually diminishing cutting speed. By contrast, while less durable, polycrystalline diamonds fracture to expose new, sharp cutting edges so that they continue to cut with speed, although with a finer, less aggressive scratch pattern.
With a protective cover that serves as a handle when open, these portable, convenient hones are only 5" long when closed. You can keep them in a toolbox or kitchen drawer without damage to the hone or your tools, and they’re compact enough to carry in a pocket. The double-sided hone has a 250x side for fast material removal and edge repair, and a 600x side for general sharpening. The 1200x is for fine sharpening and leaves a slight tooth on cutlery that makes slicing easier.
