Precision angle guides ensure accurate sharpening throughout the entire blade length and eliminate any guesswork. 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.
