HONING RODS & STROPPING. WHAT SHOULD YOU USE?
Share
Not all honing rods are created equal. When it comes to Japanese knives, using the wrong type of rod can do more harm than good.
The Big Mistake: Steel & Diamond Honing Rods
Traditional steel honing rods and especially diamond-coated rods are designed for softer, Western-style knives. Japanese knives are different. They are typically made from much harder steel, which holds a sharper edge but is less forgiving.
Using a steel or diamond rod on a Japanese knife can:
• Cause micro-chipping along the edge
• Tear or fracture the steel rather than realign it
• Shorten the life of the knife
This kind of damage often isn’t visible right away, but over time it leads to a rough edge, poor cutting performance, and more frequent sharpening.
In short: steel and diamond rods are a big mistake for Japanese knives.
The Right Choice: Ceramic Honing Rods
If you choose to use a honing rod with a Japanese knife, ceramic is the only appropriate option.
Ceramic rods:
• Are significantly finer and more controlled
• Gently realign the edge without aggressive steel removal
• Reduce the risk of chipping when used with light pressure
Even then, a ceramic rod should be used sparingly and with care. Light strokes, minimal pressure, and proper angle control are essential.
Stropping: The Preferred Maintenance Method
For many Japanese knife users, stropping is the better alternative.
Stropping doesn’t force the edge back into shape. Instead, it:
• Removes microscopic burrs
• Refines and cleans the edge
• Restores sharpness without stress on the steel
Leather, denim, or even newspaper can be used effectively. A few gentle passes per side are often all that’s needed to bring the edge back to life.
The Sharp Supply Recommendation
At Sharp Supply, our advice is simple:
• Never use steel or diamond honing rods on Japanese knives
• If using a rod, choose ceramic only
• For everyday maintenance, strop often and sharpen when needed
Respect the steel, and your knife will reward you with performance that lasts for decades — not just the first few months.
