When sharpening the blade you would see that the metal gets removed when water is added during sharpening, in the form of paste.

Depending on the type of sharpening stone that you are using, you will remove less or more metal from the knife blade.

You do not need to remove them during the sharpening process, but after sharpening the blade it’s important to remove them.

The grey residue can be quite dangerous if you cook your food without cleaning the blades. After sharpening the blade, make sure that you wash your blades using dishwashing soap and hot water.

Types of Honing Rod That Removes Metal

There are many different types of honing rods used for sharpening a knife blade, and the technique that you are using for honing mostly depends on what you are trying to achieve.

If you just need to realign the edge of the blade and maintain it well, then two or three swipes from both sides of the blade with minimum pressure should be sufficient.

  • Steel Rod: The steel rods are perfect for smooth honing and they will not remove a noticeable amount of steel from the knife blade. Most kitchen uses this type of sharpening rod.
  • Ceramic Rods: These types of rods are slightly more abrasive than steel rods and this will remove a small amount of metal.
  • Diamond Coated Rod: The rod removes a large amount of metal from the blade. Most professionals use such types of sharpening rods.

Honing vs Sharpening

Honing and sharpening are both completely different. Honing is the process of maintaining the edge of a knife that is already sharp. Honing the blade pushes the blade back and straight to the edge of the blade.

Honing the blade corrects the edge of the blade without shaving much material from the edge of the blade, and if done properly the blade will seem sharper.

If you are a professional, It is always recommended to hone your blade before use, so that you can get a better cutting experience.

On the other hand sharpening, your blade actually removes metal from the blade edge and actually sharpens the blade.

There are a variety of sharpening tools that you can use. To get real results, there is no other way than to use a sharpening stone.

To use a sharpening stone you just have to hold the edge of the blade at an angle of 20 degrees and apply pressure using the other hand. As you guide the blade across the stone the blade gets sharpened.
