Summary
A knife that crushes instead of slicing often indicates a dull blade. Our selection of professional tools includes the professional sharpening steel and various roller systems. These tools allow for regular maintenance to quickly restore an effective edge and improve safety in the kitchen.
What is the best professional sharpening steel?
Choosing the best sharpening steel relies on three key factors: the quality of the rod, a length suited to your knives, and the ergonomics of the handle.
Professional diamond or ceramic sharpening steel
- Standard grit: high abrasiveness, ideal for quickly restoring a damaged edge.
- Fine grit: recommended for regular maintenance, it refines the edge without removing too much steel.
- Extra-fine grit: preserves the sharpness of already very sharp blades.
- No grooving: diamond or ceramic rods wear out slower thanks to their smooth surface.
Choosing based on the knife's Rockwell hardness
The blade's Rockwell hardness (HRC) is a determining factor in choosing the type of steel. European knives generally range between 55 and 58 HRC, while Japanese steels often exceed 62 HRC. For the latter, a diamond or ceramic steel is recommended.
| Rockwell Hardness (HRC) | Recommended sharpening steel type | Optimal grit |
| Less than 58 HRC | Steel sharpening rod | Standard or fine |
| 58-60 HRC | Steel or ceramic sharpening rod | Fine |
| 60-63 HRC | Ceramic or diamond sharpening rod | Extra-fine |
| More than 63 HRC | Ceramic or diamond sharpening rod | Ultra-fine or specialized |
Ergonomics and safety of professional sharpening steels
The handle of a professional sharpening steel should offer a good, firm, and secure grip. Dual-material models reduce the risk of slipping, especially in wet environments. The standard length varies from 25 to 30 cm, but a 12-inch sharpening steel is ideal for large blades.
Does a sharpening steel actually sharpen?
A steel only straightens the edge without removing metal. You just need to pass it five to six times on each side at a 20° angle.
Difference between honing with a steel and sharpening with a stone
- Honing with a steel: corrects imperfections without removing steel, ideal before starting to cut.
- Sharpening with a stone: removes metal to create a new edge, longer but essential.
- Complementarity of the two: regularly using the steel extends the time between stone sharpening sessions and prevents premature wear.
Which knives not to sharpen with a steel
- Serrated blades: the rod cannot reach the inside of the bread knife's teeth.
- Asymmetrical blades: their specific bevels require a particular technique.
- Ceramic blades: even with a diamond steel, this very hard material is also fragile and can break.
Technique and maintenance for professional sharpening steels
How to properly use your sharpening steel
- 20-degree angle: the ideal inclination for a standard blade.
- 5 to 6 passes: make this movement on each side, describing an arc from the base to the tip.
- Light pressure: pressing too hard risks damaging the edge and prematurely wearing out your steel.
Maintenance and lifespan of a sharpening steel
After use, a simple rinse with clear water and careful drying are enough to prevent rust. Regular maintenance with a sharpening steel significantly reduces blade wear and ensures impeccable cutting quality.
FREQUENTLY ASKED QUESTIONS
WHAT TYPE OF SHARPENING STEEL SHOULD I CHOOSE FOR MY XINZUO OR HEZHEN KNIVES?
For daily honing of your Xinzuo or Hezhen knives, which often use German or Damascus steel with a hardness of 56 to 62 HRC, you have two main options. A steel sharpening rod is suitable for regular maintenance. If your blade is very hard, prefer a ceramic sharpening rod, as it offers more precision and causes less wear to the edge.
HOW OFTEN SHOULD I USE MY SHARPENING STEEL?
Use your steel before each major use, about once a week, or daily if you cook a lot. Five or six passes per side, maintaining a 20-degree angle, are sufficient. This simple habit will postpone the need for a deeper sharpening with diamond or on a stone by several months.
WHAT IS THE LIFESPAN OF A PROFESSIONAL SHARPENING STEEL?
This depends on the type of steel. A good professional steel sharpening rod can last between 5 and 10 years. Remember to rinse it with water and dry it thoroughly after use. A diamond model is very effective, but its abrasive surface wears out faster; it remains a very profitable investment if you own high-end knives.
CAN A SHARPENING STEEL BE USED ON JAPANESE KNIVES?
With caution, yes. Japanese knives often have a finer bevel angle (between 10 and 15°) and harder steel (beyond 60 HRC). A ceramic or diamond steel is preferable to a standard steel sharpening rod. Avoid overly abrasive steels that risk damaging the delicate edge of these blades.
WHAT IS THE DIFFERENCE BETWEEN A SHARPENING STEEL AND A ROLLER SHARPENER?
A sharpening steel realigns the blade's edge without removing metal — it is a tool for regular maintenance. A roller sharpener, on the other hand, removes material to recreate a new edge — it is a sharpening tool. For daily use, the steel is ideal. To restore a very dull blade, a roller sharpener or a sharpening stone will be more effective.
