Wüsthof Diamond Sharpener Steel, Narrow Fine 9-Inch – Diamond-Coated Sharpening Rod, Brushed Steel Handle

Diamond coating really does remove metal. My dull knife was back in action in a minute.

This steel cuts faster than a standard one thanks to the diamond coating, which is great for touch-ups but easy to overdo if you're heavy-handed. Light strokes are all you need. The narrow profile fits my knife bag well. Quality construction as expected from Wüsthof.

My kitchen knives had been neglected for years. A few minutes on this diamond steel brought back a working edge on every one of them—no whetstone required. It's not a substitute for proper sharpening on truly damaged blades, but for regular maintenance it's fantastic. The brushed handle is comfortable and the rod feels substantial.

Does sharpen effectively, but the diamond abrasion is aggressive. For daily honing I'd stick to a plain steel; I save this one for weekly or biweekly touch-ups. Fine product, just know what you're buying.

Bought this after my local knife shop recommended diamond steels. Best maintenance tool I own now. Quick, easy, effective. My chef's knife hasn't needed a full sharpening in six months.

I wanted a fine hone for my Japanese-style knives and this removed too much material for my comfort. Quality is fine, just not the right tool for hard steel. Keeping it for my German knives instead.

Ten seconds per side keeps all my edges sharp. Simple, well made, does exactly what it promises.

Between a honing steel and a full sharpening stone. I use it when my knives start to drag and it brings the edge back immediately. Narrow size is handy for storage. Recommend for people who don't want to learn whetstone technique.

As someone who cooks daily, edge maintenance matters. This diamond steel makes it effortless—two or three passes per side and the knife glides through tomatoes again. German quality is evident in the finish and feel. Excellent purchase at half price.

Bought this to maintain my Wüsthof set and it does the job well. Slight learning curve with the aggressive surface but results are undeniable. Handle grip is secure even with wet hands.
