Honing vs. Sharpening
They are not the same thing.
In the kitchen, we often say we are “sharpening” a knife when we are actually honing it. These two actions are related, but they are not the same.
Know your edge
A knife edge is created at a specific angle. Many German or American-style knives are around 20 to 22 degrees, while many Japanese-style knives are closer to 15 degrees. Knowing your knife matters because the original edge matters.
A smaller angle can slice very cleanly through delicate foods, like herbs and leafy greens, without bruising them as easily. A 20 to 22 degree edge can still do the job beautifully, but the person holding the knife needs to be gentle, use a clean slicing motion, and let the knife do the work.
Bevel and edge
The bevel is the little slope on the blade that leads down to the sharp edge.
Honing is maintenance
Honing is maintenance. It does not create a brand-new edge. Honing mainly realigns the tiny microserrations along the beveled edge.
Microserrations are the tiny, almost invisible rough points along the edge that help the knife bite into food. With regular use, those tiny points can bend out of place. Under magnification, a worn edge can look a little like split ends in hair. The knife may feel dull even though the edge is not completely gone.
Sharpening is different
Sharpening removes a small amount of worn metal from the bevel to create a fresh, clean cutting edge. When honing can no longer help, sharpening is what brings the knife back.
It does not just straighten the old edge. It reshapes the worn metal so a clean edge can cut again.
Before buying an electric or pull-through “sharpener,” read what the tool actually does. Some tools are sold as sharpeners, but they mostly maintain the edge — more like glorified honing tools. A true sharpener removes metal to create a fresh edge, so it needs to be used with care. Read the manual, follow the correct angle, and do not overuse it, because the wrong tool or too many passes can remove more of your knife’s edge than you intended.
