Dull scissors are one of those small household annoyances that can make a simple job surprisingly frustrating. Instead of making a clean cut, the blades tug at paper, chew through fabric, or leave ragged edges behind.
Before throwing out a pair that seems past its prime, check whether the problem is actually dull blades. Dirt, adhesive, rust, a loose pivot screw, or blades that have fallen out of proper adjustment can all make scissors perform poorly.
Some popular home remedies can help polish or lightly improve an edge, while proper sharpening is a better choice for scissors that have genuinely lost their cutting edge. Here are 13 ways to get your scissors working better again, from quick maintenance fixes to professional sharpening.
Cut Through Aluminum Foil
Cutting folded aluminum foil is a popular home remedy for dull scissors. Fold a sheet several times, then make a series of cuts through it from the heel of the blades toward the tips.
This can help clean and polish the cutting edges, though it shouldn’t be treated as a replacement for proper sharpening. If your scissors are very dull, foil probably won’t restore them completely.
Afterward, wipe the blades clean and test them on scrap paper.

Try Fine-Grit Sandpaper
Fine-grit sandpaper can give scissors a light cleanup and may improve a slightly dull edge. A sheet around 120 to 150 grit is commonly suggested for this purpose.
Fold the sandpaper with the abrasive side facing outward and make several full-length cuts. Use steady pressure rather than forcing the blades through the material.
This method is better suited to inexpensive household scissors than high-quality sewing or specialty shears. Those deserve a sharpening method suited to their particular blade.
Skip the Glass Jar Trick
You may have heard that cutting around the rim of a mason jar or glass bottle will sharpen scissors. The idea is that the glass edge somehow grinds the blades back into shape.
It isn’t a reliable sharpening method, and forcing scissors against glass can damage the blades or create a dangerous breakage hazard. If your scissors need real sharpening, use a sharpening tool made for the job instead.
A glass jar is better left in the pantry.

Try a Whetstone
A whetstone can sharpen some types of scissors, but it takes a little practice. The two blades should usually be separated first so you can work with the beveled side of each blade.
Place the beveled surface against the stone at the existing angle rather than guessing at a new one. Use smooth strokes in one direction and keep the angle consistent.
This method works best for people who are already comfortable sharpening knives or other blades. If you’re working with expensive fabric shears, check the manufacturer’s sharpening instructions before using a stone.
Use a Steel Rod Carefully
A steel honing rod can help with some scissors, particularly when the edges are slightly misaligned rather than badly worn.
Open the scissors and place the rod against the inside cutting edge. Draw the blade along the rod while maintaining the blade’s existing angle.
This technique takes some control, so avoid pressing hard. A honing rod can help straighten a slightly bent edge, but it won’t remove much metal or repair badly damaged blades.

Try Steel Wool for Cleaning
Steel wool is more useful for cleaning than true sharpening. If your scissors have light rust, adhesive residue, or grime on the blades, a small piece of fine steel wool can help remove it.
Wear gloves while handling steel wool and work carefully around the cutting edges. Once the blades are clean, wipe away any metal particles and apply a tiny amount of oil to the pivot.
For badly rusted scissors, a proper rust-removal method may be safer than aggressively scrubbing the cutting edge.
Use a Scissor-Sharpening Tool
A dedicated scissor sharpener is a better choice if you want to sharpen your scissors at home on a regular basis.
Some manual sharpeners have slots made specifically for scissors and guide the blade at a fixed angle. Follow the instructions for the particular sharpener rather than treating it like a knife sharpener.
Don’t force the scissors through the slot. A few controlled passes are usually preferable to repeatedly grinding away at the blades.
Try a Fine Sanding Sponge
A fine sanding sponge can work much like sandpaper for lightly cleaning and polishing a pair of household scissors.
Cut several strips through the abrasive surface using the full length of the blades. Once you’re finished, wipe the scissors down thoroughly to remove any grit.
This is a quick fix for scissors that feel a little rough, but it won’t replace professional sharpening if the blades have become seriously dull.
Check the Pivot Screw
Sometimes scissors aren’t actually dull. The pivot may simply be loose.
If the screw holding the two blades together has loosened, the blades may move apart instead of meeting correctly. That can make perfectly good scissors seem as though they have lost their edge.
Tighten the pivot screw a little at a time and test the scissors after each adjustment. Don’t overtighten it, since the blades need to move smoothly against one another.
Give the Blades a Good Cleaning
Adhesive, tape residue, fabric fibers, grease, and other buildup can make scissors feel much duller than they really are.
Wipe the blades with a soft cloth and mild soapy water when appropriate. For sticky residue, rubbing alcohol can help on many metal scissors.
Dry the blades completely afterward. Clean scissors often cut noticeably better without any sharpening at all.
Add a Drop of Oil
A tiny amount of machine oil or mineral oil at the pivot can make a stiff pair of scissors move much more smoothly.
Put one small drop where the two blades meet, then open and close the scissors several times. Wipe away any oil that spreads onto the blades.
This won’t sharpen the cutting edge, but it can improve the feel of the scissors and help prevent rust around the moving joint.
Cut the Right Materials
Using scissors for materials they weren’t made to cut is one of the quickest ways to wear them out.
Fabric shears should generally be reserved for fabric. Kitchen shears are better suited to food and kitchen tasks, while paper scissors should stay with paper and lightweight crafts.
Cutting wire, cardboard, plastic packaging, carpet, or other tough materials with ordinary household scissors can nick or damage the edge. Keeping each pair assigned to the right job can save you from frequent sharpening.
Have Them Professionally Sharpened
If you’ve tried basic cleaning and maintenance and the scissors still won’t cut properly, professional sharpening is often the safest choice.
A professional sharpener can inspect the blades, check their alignment, and remove the right amount of metal from the cutting edge. This is especially useful for quality sewing shears, tailoring scissors, hair scissors, and specialty tools.
Properly sharpened scissors can make cutting smoother and more precise. For scissors that are valuable or expensive, professional service is usually a better bet than experimenting with household objects.
You can also look for a local blade-sharpening service through a hardware store, sewing shop, or sharpening specialist.
A little maintenance can keep a good pair of scissors working for years. Clean the blades, keep the pivot moving freely, use each pair for the materials it was made for, and sharpen them properly once the edge is genuinely worn down. Sometimes the best way to rescue dull scissors isn’t a clever trick at all, it’s giving the blades the care they actually need.
