If your meat grinder isn’t working as it should, it might be time to sharpen the blades. Luckily, you don’t need a mechanic to sharpen them—you can do it yourself! In this guide, we’ll show you how to sharpen your meat grinder blades using just a sharpening stone, a cleaning rag, and some lubricating oil.


What Do You Need to Sharpen?

Typically, you’ll need to focus on the blades and plates. The blade is the cutting edge that chops the meat, and it works closely with the plate, which has holes to push the ground meat through. Over time, both can become dull from regular use.

For the blade, look for any nicks or uneven surfaces. As for the plate, check if the holes are clear and the edges around the holes are sharp. Any rounding or burring of these edges means it’s time to sharpen.


How to Sharpen Meat Grinder Blades

Here’s how to sharpen the blades of a meat grinder using a sharpening stone:


What You’ll Need

  • A sharpening stone
  • Lubricating oil
  • Clean cloth


Step 1: Select the Right Sharpening Stone

There are three main types to consider: whetstone, diamond stone, and ceramic stone.

Whetstones are great for beginners. It has two sides with different grits—coarse for initial sharpening and fine for honing the blade to a sharp edge.

The next is a diamond stone. This stone is embedded with diamonds and is much harder than a whetstone. It’s a good choice for those who want quick results and are willing to invest a bit more.

Lastly, a ceramic stone provides a fine grit. It’s perfect for achieving an extremely sharp edge. It’s less abrasive than the diamond stone. It’s ideal to use during the final sharpening phase.


Step 2: Start Sharpening the Blade and Plate

Begin by cleaning the plates and blades thoroughly to remove any meat residue or debris. Apply a few drops of lubricating oil on the stone. This will help the blade glide smoothly and prevent the stone from clogging with metal filings.

Next, hold the blade at an angle of about 15-20 degrees against the stone. Gently slide the blade across the stone in a sweeping motion, from one end of the blade to the other. Maintain the angle throughout. Repeat this process 8-10 times on each side of the blade or until you feel the edge has regained its sharpness.

Flip the stone to the finer grit side (if using a whetstone), repeat the process, and hone the edge to a fine sharpness. After sharpening, place the blade on a flat surface and wipe it with a clean cloth to remove any metal filings before reassembling your grinder.


Can You Use Other Tools and Methods to Sharpen Your Meat Grinder Blades?

Yes. You can use a honing rod or file. This is usually used for sharpening kitchen knives but can also be used for grinder blades. The honing rod realigns the edge of the blade which increases its sharpness without removing much material. This is a quick way to touch up blades that are slightly dull but not heavily worn.

Another option is an electric bench grinder if you have access to one. This tool is more aggressive and removes more material. It’s more suitable for heavily worn blades. When using one, make sure to keep the blade cool by frequently dipping it in water to prevent overheating which can weaken the steel.

If you’re looking for a more automated option, there are commercial blade sharpeners specifically designed for grinder blades. These machines can handle multiple blades at once and can help you get a consistently sharp edge with minimal effort. However, they can be more expensive and are typically used in professional settings.


How Often Do You Need to Grind Your Grinder Blade?

If you use a grinder a few times a month, you can sharpen the plate once a year. However, if you use your grinder more frequently, you might need to sharpen the plate every few months.

Keep in mind that if you notice that your grinder starts to struggle with grinding, produces inconsistent textures, or if the meat comes out squished rather than cleanly cut, then you might need to sharpen the blade sooner. The same theory applies if you notice any dulling or damage to the blades like small nicks or flat spots.




Is it safe to sharpen meat grinder blades myself?

Yes, it is safe as long as you follow the proper techniques and handle the blades carefully. Always use protective gloves and work in a stable area to prevent accidents.


What should I do if the blade still isn’t sharp after I’ve tried sharpening it?

In this case, the blade might be too worn and might require complete replacement. Regular sharpening can extend a blade’s life, but they do need to be replaced eventually.



Regular maintenance is essential for prolonging the life of your meat grinder. By following the simple steps outlined in this guide, you can keep your meat grinder in top condition for years.
