Introducing the Chef'sChoice Commercial 2100 Module, designed for convenience and ease of use. This detachable module has 3 stages for a super sharp cut. Stage 1 & 2 uses 100% diamond abrasive disks, while stage 3 uses ultra-fine proprietary stropping disks. The patented TrizorPlus edge on all kitchen knives is created by the combination of advanced diamond abrasive technology and precision engineered stropping disks. Dishwasher safe, this module is easy to use and fits any standard sized knife sharpener base -- just snap it into place! Replacement modules are available separately.
