Chef's Choice Model 250 3-Stage Hybrid Knife Sharpener, White

Combining both electric and manual stages, this 3-stage hybrid sharpener is the ideal solution for 20-degree class knives. Using 100 percent diamonds, the hardest natural substance on earth, our patented abrasives sharpen edges faster and easier. This sharpener improves cutting performance by creating 3 distinct facets set at different angles to form a longer lasting, ultra-sharp edge. The first stage sharpens straight-edge knives using medium abrasives. The second stage uses finer abrasives to hone the knife edge while the final stage delivers a polished finish using ultra-fine abrasives. Precision angle control ensures accurate sharpening throughout the entire blade length. This unit is designed to work with both straight-edge and serrated knives.WHY YOU NEED A KNIFE SHARPENER – Over time, a knife’s edge dulls under the stress of cutting. The overall performance can be significantly improved if sharpened and maintained correctly.HOW DO KNIFE SHARPENERS WORK – Good sharpening systems shape the knife edge with a coarse abrasive and polish with a finer abrasive.
