What is the difference between sharpening and honing?

In common parlance, it's not uncommon to confuse "sharpening" with "honing". However, these are two distinct stages in the complete maintenance process of a professional kitchen knife.

Honing a knife is done with a tool called a honing steel, after taking care to carry out the sharpening stage. The purpose of the honing steel is to recreate a high-performance edge on a knife that no longer produces the expected effects.

The knife is honed after sharpening. This stage is carried out on a grinding wheel and removes the worn shank from the blade. This is followed by the grinding and polishing stages, which complete the maintenance of a knife's edge.

What tools should I use to sharpen a knife?

When you want to sharpen a professional kitchen knife, you need the right tools. There are several of them, each of which enables one of the stages mentioned in the previous point to be completed.

  • A honing steel of the right size and shape (sharpening and honing).
  • A grinding wheel (sharpening).
  • A leather strop (polishing)

These professional tools are easily accessible to home users who want to maintain and sharpen their own top-of-the-range kitchen knives at home.
