Understanding Why Scissors Get Dull
Before we dive into sharpening methods, it’s helpful to understand why scissors lose their sharpness over time. Knowing the culprits behind dull blades can also guide you in preventing them from becoming blunt too quickly.
Microscopic Damage to Blades
Scissors, especially those used frequently, endure a lot of friction and pressure on their blades. Even with normal use, the fine edges of the blades can become misaligned, rolled, or chipped at a microscopic level. This damage, though often invisible to the naked eye, is the primary reason why scissors start to feel dull. The once sharp, precise edge becomes uneven and less effective at slicing through materials cleanly.
Residue and Debris Buildup
Beyond physical damage, the buildup of residue and debris also contributes to the perception of dull scissors. Adhesive from tapes, glue residue, and fibers from paper or fabric can accumulate on the blades. This sticky layer creates friction and prevents the blades from gliding smoothly against each other, making it feel like the scissors are blunt even if the edge is still reasonably sharp. Regular cleaning is therefore crucial, and sometimes, cleaning alone can significantly improve the performance of your scissors.
The Aluminum Foil Myth: Does It Really Sharpen?
You may have encountered the popular tip of using aluminum foil to sharpen scissors. The method usually involves folding a piece of aluminum foil several times and then cutting through it repeatedly. While this method is widely circulated, it’s important to understand what it actually achieves.
Why It Seems to Work (Cleaning and Burr Removal)
Cutting through aluminum foil can indeed make your scissors seem sharper temporarily. This is because the edge of the foil can help to scrub away some of the sticky residue and minor debris that have accumulated on the blades. Additionally, the foil can help to realign very small, soft burs or irregularities on the cutting edge. In essence, aluminum foil acts as a cleaning and polishing agent for your scissors’ blades.
Why It Doesn’t Actually Sharpen (Material Hardness)
However, despite the perceived improvement, aluminum foil does not actually sharpen your scissors in the true sense of the word. Sharpening involves removing metal from the blade to create a new, sharper cutting edge. Aluminum is a soft metal, significantly softer than the steel used to make scissors. Therefore, aluminum foil lacks the hardness and abrasiveness needed to grind and reshape the steel blades of your scissors. At best, it cleans and slightly polishes the existing edge, but it cannot restore a truly dull blade to its original sharpness. In fact, cutting aluminum foil, a relatively tough material, with scissors not designed for metal cutting, can potentially dull the blade over time, albeit negligibly.
Effective Methods to Sharpen Scissors
For genuinely dull scissors, you’ll need to employ methods that actually remove a tiny amount of steel to reshape the cutting edge. Here are some effective ways to sharpen your scissors, ranging from simple to more advanced techniques.
Using Sandpaper: A Gentle Sharpening Approach
Sandpaper offers a slightly abrasive surface that can gently sharpen your scissors. This method is a step up from aluminum foil and can provide a noticeable improvement, especially for moderately dull scissors.
Step-by-step guide:
- Choose the right sandpaper: Opt for a medium-grit sandpaper, around 150-200 grit. For a smoother finish, you can use finer grit paper afterwards.
- Fold the sandpaper: Fold a sheet of sandpaper in half with the abrasive sides facing outwards.
- Cut through the sandpaper: Open your scissors wide and make several cuts through the folded sandpaper, using the full length of the blades from base to tip. Repeat this process 15-20 times.
- Test and repeat: Test the sharpness of your scissors on paper or fabric. If needed, repeat the process with more cuts on the sandpaper.
- Clean the blades: After sharpening, wipe the blades clean with a damp cloth or rubbing alcohol to remove any residue from the sandpaper.

Using a Sharpening Stone: For a Professional Edge
A sharpening stone, also known as a whetstone, is a more traditional and effective tool for sharpening scissors and knives. It allows you to precisely reshape the blade edge at the correct angle.
Step-by-step guide:
- Prepare the sharpening stone: Lubricate your sharpening stone with honing oil or water, depending on the type of stone. This lubricant helps to float away metal filings and prevents the stone from clogging.
- Disassemble the scissors (optional but recommended): For easier handling and a more precise sharpening angle, you can carefully disassemble your scissors by unscrewing the pivot screw. Keep track of all the parts. If you are not comfortable disassembling them, you can sharpen them while assembled, but it requires more care.
- Identify the bevel: Examine the scissor blades to identify the beveled edge – the angled surface that forms the cutting edge. You’ll need to sharpen along this bevel.
- Sharpen one blade at a time: Hold one scissor blade with the bevel facing down on the sharpening stone at the correct angle (usually around 45 degrees, but try to match the original bevel angle).
- Consistent strokes: Using light to medium pressure, push the blade away from you along the stone, maintaining the angle. Repeat this stroke several times (around 10-20 times) on each blade side, ensuring you are sharpening along the entire length of the cutting edge. Count your strokes to apply the same amount of sharpening to each side of the blade.
- Check for burr: After sharpening one side, you might feel a slight burr (a thin, rough edge of metal) on the opposite side of the blade.
- Remove the burr: Flip the blade and lightly stroke the flat side of the blade on the stone a few times to remove the burr.
- Reassemble and test: If you disassembled your scissors, carefully reassemble them, ensuring the tension is correct. Test the sharpness by cutting paper or fabric. Repeat the sharpening process if needed.
- Clean and oil: After sharpening, clean the blades and apply a drop of oil to the pivot point for smooth operation.
Safety Note: Sharpening stones are effective but require caution. Always keep your fingers away from the cutting edge and maintain a steady hand. If you are unsure, practice on less valuable scissors first.
Using a Scissor Sharpener: The Convenient Option
For ease of use and consistent results, a dedicated scissor sharpener is an excellent investment. These sharpeners are designed specifically for scissors and often feature pre-set angles and guides, making the sharpening process simpler and safer.
Types of Scissor Sharpeners:
- Manual sharpeners: These handheld tools typically have ceramic or carbide sharpening slots. You simply draw the scissor blades through the slots a few times to sharpen them.
- Electric sharpeners: Electric sharpeners offer a faster sharpening process and may include multiple stages for honing and polishing the blades.
How to use:
- Follow manufacturer’s instructions: Each scissor sharpener may have slightly different instructions, so always refer to the manual provided.
- Clean your scissors: Ensure your scissors are clean before sharpening.
- Sharpen one blade at a time (usually): Most scissor sharpeners are designed to sharpen each blade individually.
- Consistent strokes: Follow the sharpener’s guide and draw the blades through the sharpening slots with consistent pressure and direction as instructed.
- Test and repeat: Test the sharpness and repeat the process if needed.
- Clean blades: Wipe the blades after sharpening to remove any metal filings.

Maintaining Your Scissors for Long-Lasting Sharpness
Sharpening is essential, but proper maintenance can significantly extend the sharpness of your scissors and keep them in top condition.
Regular Cleaning
Make it a habit to clean your scissors regularly, especially after cutting sticky materials. Use a soft cloth dampened with water or rubbing alcohol to wipe away residue and debris from the blades. Keeping them clean prevents friction and maintains their cutting efficiency.
Oiling the Blades
Oiling your scissors helps to keep the blades moving smoothly and prevents rust and corrosion. Apply a drop of light oil, such as sewing machine oil or mineral oil, to the pivot point where the blades meet. Open and close the scissors a few times to distribute the oil evenly. Wipe off any excess oil with a clean cloth. Oiling every few months can make a noticeable difference in the smooth operation and longevity of your scissors.
Adjusting Tension
Proper scissor tension is crucial for optimal cutting performance. If your scissors are too loose, they may bend the material instead of cutting it cleanly. If they are too tight, they can be difficult to use and may wear out faster.
How to check and adjust tension:
- Check tension: Try cutting a piece of paper. If the paper folds or doesn’t cut cleanly, the tension might be too loose. If the scissors are hard to close or feel stiff, the tension might be too tight.
- Adjust tension (if possible): Many scissors have an adjustable pivot screw. Use a small screwdriver to slightly tighten or loosen the screw until the blades meet properly and move smoothly with the right amount of resistance. Make small adjustments and test the scissors after each adjustment. If your scissors have a rivet instead of a screw, tension adjustment may not be possible.
Conclusion
While the aluminum foil trick might offer a temporary improvement by cleaning your scissor blades, it doesn’t actually sharpen them. For truly dull scissors, effective sharpening methods include using sandpaper, sharpening stones, or dedicated scissor sharpeners. Each method offers varying degrees of sharpness restoration, with sharpening stones providing the most professional edge and scissor sharpeners offering convenience.
Beyond sharpening, remember that regular cleaning, oiling, and proper tension adjustment are vital for maintaining your scissors and ensuring they remain sharp and efficient for all your cutting needs. By incorporating these sharpening and maintenance practices, you can keep your scissors performing like new, making every cutting task a breeze.
