  • A 12×12” mirror or glass sheet
  • scrape paper
  • screwdriver
  • nose pliers
  • water

Prepare Your Working Place

Now, place the glass sheet on a robust flat surface. The glass sheet needs to be flawless. Now dampen a small cloth or handkerchief by water and wipe the surface with the cloth. Make sure that the surface is just damp and don’t have any excess water. Now place the 120 grit sandpaper on the glass sheet. The water helps the paper to stick to it.


  • Firstly, safety should be the #1 priority. Wear your workman’s gloves or you will have an unpredictable accident. This gloves will keep your hand safe and give a firmer grip.
  • Now before sharpening your blades, examine the sharpness of the blades by slicing a piece of paper. This will give you a perception of how much time you need and the amount of bluntness of the blades.
  • Now push the blade on to the sandpaper at a 45-degree angle and proceed it on the surface of the sandpaper in a circular or figure eight motion. This will ensure you how uniformly the surfaces of the blades are sharpened.
  • Carry on this process at least 10 times or until your desired sharpness is achieved.

  • If you want more smoothness on the surfaces, use 600 grit instead of 120 grit and cut it according to the size of the glass sheet.
  • Now continue the whole process again. That means to push the blade on to the sandpaper at a 45-degree angle and move it on the surface of the paper in a circular or figure eight motion. This time the smoothness of the blade will be higher.

Wash It And Give It A Try

After finishing the sharpening process, give the blade a quick rinse under lukewarm water to get rid of the excess particles on it. Now let the blade dry and then assemble the grinder. Now examine if the sharpness or the efficiency has increased. To do that, grind a scrap paper and compare it with the previous sharpness.
