Product Details

A sharpening rod with a diamond coating, which should be used for dull or moderately sharp knives. The special coarse shape of the diamond grit on the sharpening rod ensures exceptional sharpening of the knife blade. The result: a smooth, sharp edge. Diamond sharpening rods are available in fine and normal grit. As these rods remove a tiny amount of metal from the knife, we recommend an additional WÜSTHOF Honing Steel for daily or weekly sharpening.

Frequently Bought Together

Other Knives
Other Knives
Material Premium forged steel engineered for lasting strength and corrosion resistance. Often stamped or made from standard steel blends that may sacrifice durability or rust resistance.
Sharpness 20% sharper than standard knives, thanks to laser-guided PEtec technology. Factory-sharpened blades that start strong but dull faster and lack precision honing.
Craftsmanship Hand-finished in Solingen, Germany with 200+ years of expertise and precision in every detail. Mass-produced or partially outsourced craftsmanship that lacks the same heritage and consistency.
Corrosion Resistance
 Exceptional rust resistance for a blade that stays beautiful for decades. Prone to staining or rust if not carefully maintained—especially with frequent kitchen use.
Edge Retention Stays sharper twice as long as ordinary knives, reducing the need to re-sharpen. Edges wear faster over time, requiring more frequent sharpening and touch-ups.
Limited Lifetime Warranty Limited lifetime warranty – a promise backed by generations of quality. Lifetime coverage may exist, but with less transparency and variable service depending on the brand.

Questions? We Have Answers

What sets WÜSTHOF knives apart from other brands?

WÜSTHOF is one of the few brands permitted to use the label “Made in Solingen” on our knives rather than the less restricted “Made in Germany.” Solingen, Germany is the steel manufacturing capital of the world and, as such, needed to take precautionary measures against fraudulent products bearing the prestigious name, “Solingen.” In 1938, Solingen became the only city in the world whose name is a registered trademark. To bear the name Solingen, all key manufacturing stages must have been processed and finished within Solingen, and the product must meet strict quality standards. This means that even cutlery manufactured entirely within Solingen’s town boundary may not be entitled to bear the name Solingen if it does not meet these required quality standards.

Some of our competitors use the label “Made in Germany,” which does not carry the same significance. We have the honor of labeling our products “Made in Solingen.”

What is Precision Edge Technology (PEtec)

WÜSTHOF’s proprietary state-of-the-art technology incorporates a computer-controlled method for putting the edge on forged knives. Using laser-guided precision, our knives are 20% sharper with twice the edge retention. All forged knives are manufactured using PEtec.

What do the numbers printed on my blade mean?

The number etched on your blade indicates the year it was made — just add “20” in front of it.

In some cases, you might see a second number, which shows the blade length in centimeters.

There is no item number printed on the blade.

Examples:

• “25” means the blade was made in 2025.

• “22 / 20” means the blade was made in 2022 and is 20 cm long.

What is the difference between forged and laser-cut stamped knives?

Forged knives go through over 40 steps in our factory to create the top quality blades WÜSTHOF has to offer. Forged knives include a bolster, which helps to balance the knife. Laser-cut stamped blades go through 14 steps in our factory, and are more economically priced. They are lighter in weight, and do not have a bolster.

What are the most important knives to start a set?

The most important knife in any kitchen is the chef’s knife, and after that, it depends on your own personal preferences when cooking.

How do I keep my knives sharp?

WÜSTHOF knives can be honed and sharpened using a hand-held sharpener, an electric sharpener, a sharpening or honing steel, or a whetstone. We recommend using the same brand sharpener as your knife collection, to ensure that the material used is the correct hardness for the steel on your knives. Our sharpening angle for standard blades is 14˚ per side, and for Asian-style blades (Santokus, Nakiris) is 10˚ per side. We offer a variety of sharpening products with pre-set angles.

Elizabeth K. (5/5)

Manager

"The knife sharpener removes metal very well and sides in sharpening, but, I am used to using a twelve inch and a fourteen inch steal for honing the edge an my knives and the short ten inch is hard to get used to, especially for long knives. I wish it was offered in a larger length."
