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.
The hones have a slim profile to provide access and control in confined areas, making it easier to maintain original relief angles. With abrasive right to the edge of the hone, they are available in 250x, 600x and 1200x grits for rough, general and fine sharpening, plus a 150x grit for rapid material removal to repair nicks or other damage.
