How to Sharpen a Knife With a Grinder

A bench grinder is a powerful and useful tool for anyone who is intending to work with woods and knife repair. It has a grinding wheel that rotates at a very high speed and can trim off pieces of wood, plastic, or even metals. Not only for grinding, but it can also sharpen the blades of all kinds. Many professional knife sharpeners use a bench grinder to explore their creative skills. 

Buying a new blade is expensive if compared to getting a knife blade sharpened. With the help of a grinder, you can sharpen any knives for as many times you want. Even if you are a chef and your various knives cost you several thousand dollars, you can use the grinder as a boon. 

Here are some tips to get perfectly sharpened edge of a blade using a bench grinder.

  • VICE: You may think that it is a good idea to use a vice because of the high speed of a bench grinder. But, you should never use a clamp. It will mostly keep the blade in one place, but after that, it may change the alignment. Sharpening a knife is not a linear process.
  • ANGLE: Do not sharpen a blade with its side flush against the grinder. Many people make a mistake by keeping the edge flat on the bench grinder wheel. It can make the blade shine but can’t make it sharp. So, always maintain the angle towards the grinding wheel to get a sharp edge of the blade.
  • MOVEMENT: Most flat knife blades have a curvature. So, always follow the natural curve of the blade while using the bench grinder.

Tip: Always wear protective gear while sharpening the knives. Keep your eyes and hands covered with quality protectors while operating the grinding or sanding machine.
