What You'll Learn
Using toothpaste to sharpen blades
While some sources suggest that using toothpaste to sharpen blades is a temporary solution, it is still a good skill to have in a pinch. Toothpaste is a mild abrasive and is non-toxic, so it can be used to sharpen blades. However, it is important to note that toothpaste is not meant for sharpening steel, and there might be better options available.
To sharpen your Norelco electric shaver blades using toothpaste, first, disassemble the razor head, ensuring you know how it comes apart so that it can be easily reassembled. Clean the razor head to remove any debris. Then, apply a pea-sized amount of toothpaste to each blade. Avoid using toothpaste with "extreme whitening" or similar variants as they have larger "gritty particles" that won't be as effective for sharpening. Once the blades are covered in toothpaste, reassemble the razor head and turn on the razor for 30 seconds. Finally, clean off the toothpaste and rinse the blades with warm water. Dry the blades and apply a small amount of baby oil before putting your electric shaver back together.
Some users have reported success with this method, claiming that their razor shaves better than new after using toothpaste. However, others have expressed skepticism, noting that toothpaste may not be abrasive enough to effectively sharpen blades. It is worth noting that this method may not work for all types of razors, and it is important to exercise caution when handling sharp blades.
In addition to using toothpaste, there are other methods to sharpen Norelco electric shaver blades. One method involves using a flat piece of glass, similar to how double-edged razor blades were sharpened on a sheet of glass during World War II when steel was scarce. Another method is to use the Vollco Replacement Shaver Heads VSH-2 Black, which are compatible with several models of Philips Norelco razors and have received positive reviews for their effectiveness and ease of use.

Sharpening blades with a sheet of glass
To sharpen blades with a sheet of glass, you will need a flat piece of glass (a mirror or picture frame glass will do) and a small brush to clean the shaver and its heads.
First, use the brush to clean out any hair in the body of the shaver. Do not use water for this step. Next, rotate the white wheel to release the cutters and remove them from their housing. Clean the housing and the cutters with the brush and running tap water. Close the drain in your sink before sliding out only one of the cutters to avoid losing any parts. Again, clean the cutter and shield screen with the brush and running water, as junk can get trapped in the cutters. Dry the cutter with a tissue and replace it in the shield screen before removing the next cutter. It is not recommended to remove all the cutters at once to avoid mixing them up.
Now, you can begin sharpening the blades on the glass. Hold the bare blades against the bottom of the glass sheet and drag them across the surface. Ensure that you drag the blade with the blade edge towards the glass, rather than away, as if you are trying to shave off the top layer. Only light pressure is needed, beginning with the base of the blade (the heel) and ending at the tip. Repeat this motion about 20 times on each side of the blade. Alternating between sides of the blade is important to ensure an even sharpening. Draw the blade against the glass 10 times on each side, then 5 times, then 3 times, then alternate single strokes back and forth 6 times. Stop when you've raised a burr on the blade's edge. You can carefully test this with your fingernail by applying it to the edge of the blade.

Using a ceramic plate or cup to sharpen blades
Norelco electric shavers can be expensive, so it's understandable that you may want to sharpen the blades yourself instead of buying a replacement. One method that has been suggested is to use a ceramic plate or cup. Ceramic cups are known to work well for sharpening kitchen knives, and the same principle can be applied to shaver blades.
To sharpen blades using a ceramic plate or cup, you can use the weight of the shaver by holding the bare blades against the bottom of the ceramic surface and running it for a few seconds. This method may be preferable to using a diamond sharpener, which can be tricky and requires more specialized equipment. However, it's important to note that ceramic knives are more challenging to sharpen than steel knives, and the process may not be as straightforward as with other materials.
One challenge with sharpening ceramic blades is that they are more fragile than steel blades. As a result, you need to be careful not to snap the blade while trying to sharpen it. It's recommended to use a proper knife sharpener, such as the Spyderco Sharpmaker, rather than attempting to sharpen the blade by hand. Additionally, consistent angles will create a better edge, so it's important to take your time and maintain a steady hand during the sharpening process.
If you do choose to use a diamond sharpener, there are a few options available. You can use a diamond sharpening stone, which is a flat grinding stone with embedded grit diamond, or a diamond file, which is a bit trickier and requires a knife rest. Another option is to purchase a diamond-wheel home sharpener, which can be manual or battery-powered. These sharpeners can fix chips in the blade and restore it to a smooth, sharp edge.
In conclusion, while it is possible to sharpen Norelco electric shaver blades using a ceramic plate or cup, it may be more effective to use a diamond sharpener, especially for ceramic blades. Whichever method you choose, take your time and be cautious to avoid damaging the blades or compromising their sharpness.

Knocking off oxidation on blades
Oxidation is a natural process that can leave orange stains on your blades, making them look rusty. To knock off oxidation from your blades, you can try the following methods:
Using White Vinegar
Soak a cloth or paper towel in white vinegar and apply it to the rusted portion of the blade. You can also place the blade in a bowl of white vinegar for up to 5 minutes. After soaking, wipe the blade down with a clean cloth to remove any remaining vinegar.
Using Baking Soda
Make a paste from baking soda and water, or lemon juice, and apply it to the blade. This will help break down the rust. Clean the blade beforehand to remove any dirt or loose rust.
Using Penetrating Oil
Apply penetrating oil, such as WD-40 or Liquid Wrench, to the rusted portion of the blade. Then, use fine-grit sandpaper (400 grit or higher) to scrub the area before wiping away the oil. Reapply the oil and let it soak for a few minutes if necessary. Always use penetrating oils in well-ventilated areas and take caution when handling sharp blades that have been treated with oil.
Using Metal Polish
Apply a metal polish such as Flitz to the blade and use a jeweler's polishing cloth to remove the oxidation. You can also use #0000 steel wool with moderate pressure, following the grind lines perpendicular to the spine of the blade.
Preventing Future Oxidation
To prevent oxidation from occurring in the first place, clean and dry your blades after each use, and store them with a coat of oil if they are not used frequently. Regularly inspect your blades for any signs of oxidation or rust and clean them occasionally to remove dirt or dust that can trap moisture and lead to rusting.

Using third-party sharpening heads
Norelco electric shavers are designed with detachable shaving heads that contain three small, round cutters. Over time, the edges of these cutters may dull, reducing the razor's performance. While Norelco recommends purchasing replacement shaving heads, third-party manufacturers offer alternative solutions in the form of sharpening heads. Here's a guide on using third-party sharpening heads:
Step 1: Power Off and Disconnect: Start by switching off your Norelco razor and disconnecting its charging cord. This is an essential safety precaution before proceeding with any maintenance or cleaning tasks.
Step 2: Remove the Shaving Head Holder: Grip the edges of the shaving head holder and gently pull it away from the razor. You may need to apply a slight amount of force, but be careful not to damage any components.
Step 3: Access the Cutters: Turn the shaving head holder over and locate the retaining frame. On some models, the frame is secured with a screw, while on others, it slides out. Carefully remove the retaining frame to access the cutters and sharpening heads.
Step 4: Clean the Components: Use a small brush to remove any hair or shaving debris that has collected on the cutters, sharpening heads, and other components. It's important to ensure these parts are clean before proceeding with sharpening.
Step 5: Rinse and Dry: Rinse the components, including the cutters and sharpening heads, with clean water. Gently pat them dry using a paper towel or a soft washcloth. Make sure they are thoroughly dried before proceeding to the next step.
Step 6: Install the Third-Party Sharpening Heads: Follow the instructions provided with your chosen third-party sharpening heads. These sharpening heads are designed to hone the edges of the cutters. Carefully install them according to the manufacturer's instructions, ensuring a secure fit.
Step 7: Reassemble the Shaver: Once the sharpening heads are in place, carefully reassemble the shaving head holder. Replace the retaining frame and reinstall the entire assembly onto the razor. Ensure that all components are securely attached.
Step 8: Test the Razor: With the third-party sharpening heads installed, turn on the razor and allow it to operate for a brief period (around 30 seconds). Then, power off the razor and carefully inspect the cutters and sharpening heads for any signs of wear or uneven sharpening.
Step 9: Repeat as Needed: Depending on the condition of your cutters and the effectiveness of the sharpening heads, you may need to repeat the process. Always exercise caution and follow the manufacturer's instructions for the sharpening heads.
Step 10: Final Assembly and Cleaning: Once you're satisfied with the sharpening results, perform a final assembly by reinstalling the shaving head holder, ensuring all components are secure. Clean the razor by running it under hot water to remove any remaining debris or residue.
It's important to carefully follow the instructions provided with your chosen third-party sharpening heads, as different products may have specific requirements or variations in the installation process. Additionally, always exercise caution when handling the razor's components to avoid damage or injury.
