Engineered To Perform

Create the world’s best knife sharpener, that was Chef’sChoice’s goal back in 1985. Since then, Chef’sChoice sharpeners have become synonymous with unparalleled quality, and premier technology. Today, they continue to only offer pinnacle products for those passionate about the kitchen.

Over time, a knife’s edge dulls under the stress of cutting. The overall performance can be significantly improved if sharpened and maintained correctly. Good sharpening systems shape the knife edge with a coarse abrasive and polish with a finer abrasive.

Compact and lightning-fast, this professional sharpener uses advanced technology to sharpen both fine edge (straight edge) and serrated knives. 2-Stage sharpening provides arch-shaped edges, which are stronger and longer lasting than hollow ground or conventional “V” edges. Stage 1 uses 100% fine diamond abrasives to create the first bevel and Stage 2 ultra-hones the edge using advanced micron size 100% diamond abrasives to complete the second bevel. The precisely formed conical diamond abrasive disks gently apply optimal sharpening pressure, guaranteed to never detemper the edge. Highly precise knife guides automatically position and stabilize the knife as you sharpen for fast, foolproof results.

The Model 320 is ideal for sharpening all types of knives, including kitchen, household, sporting and pocket knives. This compact unit features resilient elastomeric feet that hold the unit securely to the work surface. Engineered and assembled in the USA. This professional electric 2-Stage knife sharpener sharpens both straight edge and serrated knives to better than factory edges, in just minutes.
