What Is the Best Thing to Sharpen Knives With?

The main tools you can use to sharpen your knife include whetstones (sharpening stones), electric sharpeners, honing rods, and leather strops. There are also a variety of handheld and manual sharpeners available.

  • Whetstones (Sharpening Stones): These are considered one of the best options for sharpening a knife, as they are gentle on the blade while allowing you to maintain your knife’s original angle. However they take more time and practice to use than electric sharpeners.
  • Electric Knife Sharpeners: These are the easiest tool to use, but they tend to take more of your knife’s edge than sharpening stones. However, electric sharpeners preserve the blade’s quality better than manual sharpeners.
  • Honing Rods & Leather Strops: These are used to refine the blade after you have sharpened your knife. Honing rods remove burr, which is the excess metal that accumulates on the blade after sharpening. Leather strops refine the process even more by removing any tiny remaining scraps.
