Step 1: Clean The Knife Properly

Things To Keep In Mind While Sharpening A Knife

Sharpening a knife is a very simple procedure if you understand the following tips:

  • Always wear safety gear before sharpening knives.
  • Because the grinding wheel rotates at a rapid speed, the blade may become extremely hot. As a result, it can become brittle and shatter easily. To avoid this, keep a bucket of cool water beside you and dip your knife into it to cool it down.
  • When using a grinder, be sure your knife is held at the proper angle. Do not overstretch yourself.
  • Use knife sharpening wheels, which are specifically designed for sharpening, if you're sharpening your knife on a grinder.
  • When sharpening a knife, always follow the natural curve of the blade. As you sharpen the blade, the bench grinder will pull it into line, so pay attention to it. This movement prevents the knife from grinding in one position. It also helps in the timely movement of the blade.
  • Bench grinders spin at a high rate, making it difficult to sharpen a knife. Reduce the bench grinder's speed and make sure it's still fast enough to sharpen the tool.
