The Asian Style Replacement Module for the Chef's Choice Model 2100 allows you to easily sharpen knives at a 15-degree bevel. Because this module just slides into the Model 2100, you can switch between it and The Standard 20-degree Module in just seconds. In a high volume commercial setting, a replacement module can be used while the original is out for cleaning. The module features high quality diamond abrasives for fast sharpening and razor-sharp edges. Engineered and assembled in the USA.
