How to Sharpen a Meat Grinder
Cooked and raw meat is processed through a meat grinder. (old meat grinder image by Igor Golovnov from

Meat grinders are kitchen appliances that make mincing raw and cooked meat simple. Users put meat into a funnel. From there, the machine grinds the meat through a screw conveyor, then pushes it through a knife plate. Periodic sharpening of a meat grinder helps keep it functioning properly and prevents damage to the machine.

Skill level:

Things you need

  • Safety gloves
  • 120 and 600 grit sandpaper
  • Pane of glass or mirror 1 foot by 1 foot
  • Screwdriver
  • Needle-nose pliers
  • Water
  • Clean, used rags
  • Scrap paper
  • Sharpening tool

  1. 1

    Select the sharpening tool such as a handheld knife sharpener or sharpening stone to sharpen the meat grinder's blades. Lay your pane of glass or mirror on a flat surface and wipe the glass with a damp rag. Apply a piece of 120 grit sandpaper to the damp glass. The small amount of water on the glass should hold the sandpaper in place.

  2. 2

    Carefully disassemble your meat grinder, laying all of the parts out on a flat surface in the order that you remove them. Sharpen each piece, one at a time, and lay each finished piece back down in order. This will help you assemble the meat grinder properly when you are finished sharpening its parts.

  3. 3

    Put on a pair of safety gloves to protect your hands from getting cut by the blades and to give you better traction on the pieces. Test the sharpness of your meat grinder blade by using it to cut a small piece of scrap paper. Note how difficult or easily the blade cuts through the paper so that you can compare after sharpening.

  4. 4

    Press the meat grinder blade down against the sandpaper at a 45 degree angle. Move the blade across the sand paper in a figure eight pattern about 10 times. Use a dry rag to wipe any sandings off of the blade. Repeat this process for every piece of the meat grinder's blades.

  5. 5

    Remove the sheet of 120 grit sandpaper from the glass and replace it with a sheet of 600 grit sand paper. You might need to re-wet the glass' surface to ensure the sand paper sticks to it. Press each meat grinder part across the sand paper in a figure eight motion five times.

  6. 6

    Rinse each sharpened part under running water and allow it to dry completely. Test the sharpness of the blade by using it to cut another piece of scrap paper. Compare the cut to the first test. If it seems to cut the paper easier and without any resistance, you can reassemble your meat grinder. If not, perform step 5 again and retest.
