Easily apply a seriously sharp, durable edge to both ceramic and steel knives, in one simple to use sharpening system! There is no need to send your ceramic knives back to the factory for sharpening or to buy a separate knife sharpener to sharpen them! The 702 uses an advanced diamond abrasive technology to quickly apply an incredibly sharp and durable edge to both ceramic and steel knives.
 

 

The Model 702 uses 2-Stage sharpening; precision flexible guides for accurate control of the blade and sharpening angle; and the advanced diamond abrasive technology that has made Chef’sChoice sharpeners the choice of discerning consumers, leading chefs and blade enthusiasts worldwide.

Both ceramic and steel knives go through Stages 1 and 2 of the sharpener for first time sharpening and use Stage 2 for subsequent edge touch-ups. The stages work to create our signature arch-shaped edge that is widely recognized for astonishing sharpness and durability. This arch-shaped edge structure is known to be stronger and longer lasting than hollow ground or conventional “V” type edges. The Diamond UltraFlex™ finishing stage has been engineered with a proprietary blend of materials to Strop/Finish both ceramic and metal knives and apply a razor sharp, factory grade edge.
