The Wusthof diamond sharpening steel is a professional-grade honing and sharpening tool designed to maintain a keen edge on kitchen knives between full sharpening sessions. Unlike a standard honing steel, the diamond-coated surface removes a small amount of material with each pass, making it suitable for restoring an edge that has begun to dull rather than simply realigning it. At 25.4cm in usable length, it accommodates chef's knives and longer blades comfortably.

In a working kitchen, knife maintenance is a daily discipline. A diamond steel used correctly at the start and during service keeps blades cutting cleanly through prep, reducing the effort required and the risk of the knife slipping on food. The 280g weight sits firmly in hand without being tiring during regular use, and the diamond steel construction holds up reliably to the demands of a professional kitchen environment.

  • Keeps knife edges sharp and consistent throughout a full service shift
  • Suitable for daily use on high-carbon stainless and forged steel blades
  • Reduces the frequency of full wheel or whetstone sharpening sessions
  • Practical for use at the pass or prep station without specialist equipment

No installation is required. The steel is a hand tool and needs no fixed mounting or power source. It is worth noting that diamond steels remove more material than a smooth or ceramic honing rod, so technique matters — overly aggressive use can shorten blade life faster than necessary. Staff unfamiliar with sharpening steels may benefit from brief guidance before use.

This steel is well suited to professional kitchens where knife maintenance is taken seriously and blades are used heavily across long prep and service periods. It pairs naturally with Wusthof forged knives but works with most quality kitchen knife brands. If your operation requires a steel for very heavy daily use across a large brigade, it is worth discussing whether a different grit or style of sharpening tool would be more appropriate for your setup. The team is happy to advise.

Frequently asked questions

What is the difference between a diamond steel and a standard honing steel?

A standard honing steel realigns the edge of a blade without removing significant material, whereas a diamond steel has an abrasive coating that actively removes a small amount of metal to reshape a dulled edge. This makes a diamond steel more effective when a knife has lost its edge entirely, but it does mean technique is important — too much pressure or too steep an angle can wear the blade faster than necessary.

Is this steel suitable for all types of kitchen knife?

It is well suited to forged high-carbon stainless steel knives, including Wusthof's own range, and works with most quality professional kitchen blades. It is generally not recommended for use on Japanese knives with very hard, brittle steel or single-bevel blades, as the abrasive action can damage the edge geometry on those styles — a whetstone is usually preferable for that type of blade.

How often should kitchen staff use a diamond steel during service?

Most professional kitchens use a honing or sharpening steel at the start of service and periodically during heavy prep. With a diamond steel specifically, a few careful passes at the correct angle is typically sufficient — it does not need to be used as frequently as a smooth honing rod because it is actively reshaping the edge rather than just maintaining it. Over-use will shorten blade life, so a light, consistent approach works best.
