Sharpening Your Food Processor Blades: What You Need to Know

Sharpening your food processor blades is an important part of maintaining the appliance and ensuring that it works efficiently. It can be a tricky process, however, so it’s important to know what you need before you start.

The first thing you will need is a sharpening stone or honing steel. This should be used regularly to keep the blades in good condition and prevent them from becoming dull over time. You may also want to invest in a blade guard to help protect the blades while they are being sharpened.

Next, make sure that you have some safety equipment, such as goggles and gloves, when working with the blades, as they can become very sharp during this process. Once these items are ready, take apart your food processor and remove any parts that could get in the way of sharpening, such as rubber gaskets or plastic covers.

Now it’s time to begin sharpening. Start by running each blade along the stone or honing steel at an angle of about 20 degrees for several passes on both sides until all edges feel smooth again. Make sure not to apply too much pressure, as this could damage the blade itself or cause injury if done incorrectly.

Once finished, reassemble your food processor and test out its performance. If everything looks good, then congratulations; you have successfully sharpened your food processor blades without any issues. If there are still problems after trying again, then consider taking it to a professional for further assistance before using it again for cooking purposes.

Sharpening your food processor blades is an essential part of keeping them in good condition and ensuring they perform their best. Now that you know what you need to know, let’s take a look at the step-by-step guide to sharpening them.

Key Takeaway: Sharpening food processor blades is a tricky process, but with the right safety equipment and technique, you can do it yourself. Use a sharpening stone or honing steel, wear goggles and gloves for safety, angle the blade at 20 degrees when sharpening both sides, reassemble and test performance before use.

Step-by-Step Guide to Sharpening Your Food Processor Blades

With a few simple steps, you can keep your blades sharp and working like new ones.

Safety First

Before beginning any maintenance or repair on a food processor, it’s important to unplug the device from its power source and take all necessary safety precautions. Wear protective gloves when handling the blade to avoid injury.

Gather Your Supplies

You will need several items in order to sharpen your food processor blades properly. These include an old towel, a container filled with warm water, dish soap, a soft-bristled brush (such as an old toothbrush), kitchen shears or scissors for cutting away debris from around the blade, steel wool pads of grade 0000 for polishing metal surfaces and some mineral oil for lubrication.

Step 1: Unplug the Food Processor

Before you begin sharpening your food processor blades, it is important to unplug the appliance from its power source. This will ensure that no one gets hurt while you are working on the blades.

Step 2: Remove the Blades From the Food Processor

Once you have unplugged the food processor, carefully remove all of the blades from inside it. Place them in a safe area where they won’t be disturbed or damaged during this process.

Step 3: Sharpen with Sandpaper

Using fine-grit sandpaper, gently sharpen each blade until it is as sharp as possible without damaging its edges or dulling its surface. Make sure to use even strokes and do not apply too much pressure when doing so. It may take several passes over each blade before they are sufficiently sharpened.

Step 4: Clean Blades Thoroughly

After you have finished sharpening your food processor blades, make sure to clean them thoroughly with warm water and soap before putting them back into the machine. This will help keep your appliance running smoothly for years to come.

Once all of your blades have been cleaned and dried off completely, reassemble your food processor by placing each blade back into its designated slots within the machine’s housing unit. Make sure that everything is securely fastened before plugging it back in and using it again.

By following these simple steps, you can easily sharpen your food processor blades to keep them in top condition. Now let’s look at some tips for maintaining them over time.

Tips for Maintaining Your Food Processor Blades

Maintaining your food processor blades is essential for keeping them in top condition and ensuring that they last as long as possible. Here are some tips to help you keep your blades sharp and efficient:


Cleaning your food processor blades regularly will help prevent rust and corrosion, which can damage the blade’s edge over time. Make sure to use a soft cloth or brush when cleaning the blades, as harsh scrubbing could cause scratches or other damage. Additionally, make sure to dry off any moisture from the blade after washing it.


Sharpening your food processor blades periodically is important for maintaining their effectiveness. To sharpen them, use honing steel specifically designed for kitchen knives – never use an ordinary metal file. Hold the honing steel at an angle of 20 degrees against each side of the blade while running it along its length several times on both sides until you feel a smooth finish on both edges of the blade.

Avoid Overuse

When using your food processor, try not to overload it with too much work in one go; this can cause undue strain on its components and lead to wear and tear over time. Instead, break up larger tasks into smaller batches so that all parts of the machine get equal rest periods between uses. This will ensure that everything runs smoothly and efficiently without putting too much stress on any component, such as its motor or cutting blades.

Proper storage is key in preserving your food processor’s performance level over time. Always store it away from direct sunlight or heat sources such as radiators or ovens, which could warp plastic components like lids and handles if exposed for extended periods of time. Additionally, make sure that all removable parts (such as bowls) are stored separately so they don’t rub against each other during transportation; this will help avoid scratches or dents, which may affect their performance down the line.

FAQs in Relation to How to Sharpen Your Food Processor Blades

How do I make my blades sharp again?

Sharpening blades is a simple process that can be done with either a sharpening stone or an electric sharpener. To sharpen with a stone, start by wetting the blade and the stone to reduce friction. Then, hold the blade at an angle of 10-15 degrees against the stone and draw it towards you in long strokes. Repeat this process until you have achieved your desired level of sharpness. For electric sharpeners, follow the instructions provided in your device’s manual for the best results. With regular maintenance, you should be able to keep your blades razor-sharp.

How do I make my blender blades sharper?

Sharpening your blender blades is a simple process. First, unplug the blender and remove the blade assembly from the base. Next, use a sharpening stone or fine-grit sandpaper to gently sharpen each blade edge in one direction. Finally, rinse off any residue with warm water and reassemble the blender before plugging it back in. Ensure extra care when handling sharp objects like blades to avoid injury.

Does salt sharpen blender blades?

No, salt does not sharpen blender blades. Blender blades are made of metal, and the abrasive nature of salt can actually cause them to wear down over time. Instead, it is best to clean your blender blade regularly with warm soapy water and a soft cloth or brush. Additionally, you may want to use a special cleaning solution specifically designed for blenders if you find that your blade has become dull or rusty. These steps will help keep your blender in top condition and ensure that it works efficiently for years to come.

Can stainless steel blades be sharpened?

Yes, stainless steel blades can be sharpened. However, the process is not as straightforward as with other materials, such as carbon steel. It requires special equipment and techniques to sharpen stainless steel blades correctly without damaging them. Additionally, it’s important to use a lubricant while sharpening to reduce friction and heat buildup, which can cause damage or even breakage of the blade. With proper care and maintenance, however, you can keep your stainless steel blades in top condition for years to come.


With the right tools and knowledge, you can easily keep your food processor blades in tip-top shape. By following our step-by-step guide, tips for maintenance, and troubleshooting common issues with food processor blades, you’ll be able to sharpen your food processor blades like a pro.
