Wusthof PEtec Electric Knife Sharpener

No, this sharpener is specifically engineered for straight-edge blades only. Using it on serrated knives will damage both the blade's teeth and the sharpener's abrasive wheels.

The sharpener uses a pre-set 14-degree angle per side. While it is optimized for Wusthof knives, it will work on any straight-edge kitchen knife that benefits from a 14-degree edge, which is standard for many high-quality European-style blades.

The three-stage process guides your knife through progressive levels of refinement. The first two stages use diamond abrasives to reshape and sharpen the edge, while the final stage hones and polishes it for a smooth, razor-sharp finish.

It is designed for ease of use. The integrated angle guides remove the guesswork by holding the knife at the correct position automatically, so you simply pull the blade through each slot without needing to master manual sharpening techniques.

The housing is made of durable plastic that can be wiped clean with a damp cloth. Because it uses diamond abrasives, you generally do not need to oil or lubricate the internal components, but you should ensure the unit is unplugged before cleaning.
