This professional sharpener is compact and incredibly fast, utilizing advanced technology to sharpen both fine and serrated knives. The two-stage honing process creates curved edges that are stronger and last longer than hollow-ground or traditional "V" edges. In Stage 1, 100% fine diamond abrasives are used to create the first phase, and in Stage 2, the edge is ultra-polished with highly developed 100% micron-sized diamond abrasives to complete the second phase. Precisely shaped, conical diamond grinding wheels apply the optimal sharpening pressure gently, ensuring that they never lose their sharpness. The high-precision knife guides automatically position and stabilize the knife during sharpening, resulting in quick and reliable results.
