Chef's Choice Ceramic + Steel Diamond Hone Electric Knife Sharpener # 702

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.

Featuring an elegant design with two sharpening stages and precision knife guides, the Chef’sChoice® Model 702 is totally safe for all quality knives and will sharpen kitchen, household, fish fillet, pocket and serrated knives―ceramic or metal.

Ceramic Knives:

Ceramic knives, sold in increasing numbers during the past 20 years, have attracted much attention because of their initial sharpness, light weight and claim to not interact with food. Major drawbacks to wider use is their tendency to break orchip if dropped or used on hard surfaces―and the lack of convenient, inexpensive sharpening products to restore their edge. Ceramic knives often have to be sent back to the factory for factory quality edge restoration. Currently available sharpeners use messy water based abrasives, grinding belts and/or only remove major chips from the edge, without restoring a precision factory type edge.

The Model 702 is the ultimate, affordable, in home solution for sharpening ceramic knives with a precision that equals or surpasses the highest quality factory edges! It will remove most chipped edges and apply our signature double-bevel, arch-shaped edge that is longer-lasting and razor sharp. 

How It Works:

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. 


Using an advanced diamond abrasive technology, this ground-breaking electric sharpener quickly apply an incredibly sharp and durable 15 degree edge to both CERAMIC and STEEL knives:
