How to Tell If Your Scissors Need Sharpening

Blunt scissors are one of those things you put up with for far too long — until you use a sharp pair and wonder how you ever managed.

Whether you're using kitchen scissors to break down a chicken, dressmaking scissors to cut fabric, or general household scissors around the house, the sharpness of your blades makes a significant difference to the quality and ease of your work. The problem is that scissors blunt gradually, so it's easy not to notice until they're really struggling.

Here are the telltale signs that your scissors need sharpening — and what to do about it.

1. They're Pushing or Folding the Material Instead of Cutting It

This is the most obvious sign. Sharp scissors slice cleanly through material in a single, smooth motion. Blunt scissors push the material away or fold it between the blades rather than cutting through it.

If you find yourself having to force your scissors through fabric, paper, or food — or if the material bunches up near the tips — your scissors almost certainly need sharpening.

2. You Need to Use More Force Than Usual

Sharp scissors feel almost effortless. If you're squeezing harder than you used to, or your hand is aching after a cutting session that wouldn't normally cause any fatigue, that's a clear sign the blades have dulled.

This is particularly noticeable with kitchen scissors cutting through tougher materials like poultry bones, herbs, or packaging, and with dressmaking scissors cutting through multiple layers of fabric.

3. The Cut Is Ragged or Uneven

Run your scissors along a piece of paper or fabric and look at the cut edge. A sharp pair of scissors produces a clean, straight line. A blunt pair leaves a ragged, torn, or uneven edge — particularly towards the tips of the blades, which tend to dull first.

For hairdressing scissors, this is especially important. Blunt blades can split and damage hair rather than cutting it cleanly, leading to frizz and split ends that your clients will notice.

4. The Scissors Are Snagging or Catching

If your scissors are catching on the material mid-cut — stopping suddenly or requiring a little jerk to continue — the blades have developed nicks or uneven spots along the cutting edge. This is common with scissors that have been used on tough materials or dropped on a hard surface.

Snagging is different from general bluntness and usually requires professional sharpening to remove the damaged section of the blade and restore a smooth, even edge.

5. They're Leaving Marks on Fabric

For dressmaking and tailoring scissors, a key test is to cut a piece of fine fabric — silk or chiffon works well. Sharp scissors glide through cleanly without leaving any marks on the cut edge. Blunt scissors drag and pull at the fibres, leaving a slightly frayed or marked edge even on a straight cut.

If your fabric scissors are leaving marks, it's time for a sharpen.

6. The Paper Test

Not sure whether your scissors are blunt? Try the paper test. Take a single sheet of standard printer paper and cut through it in one smooth motion from the base of the blades to the tips.

• Sharp scissors — cut cleanly and smoothly all the way to the tip, with no tearing or resistance
• Blunt scissors — struggle, tear, or require multiple attempts to complete the cut, especially near the tips

This is a quick and reliable way to check the sharpness of any pair of scissors, regardless of what they're normally used for.

7. They Haven't Been Sharpened in Over a Year

Even if your scissors feel fine, if you can't remember the last time they were sharpened — or if they've never been professionally sharpened — they're almost certainly not as sharp as they could be.

As a general rule:

• Kitchen scissors — sharpen once a year, or more frequently with heavy use
• Dressmaking and fabric scissors — sharpen every 6–12 months depending on use
  
• General household scissors — sharpen every 1–2 years

Regular sharpening keeps your scissors in peak condition and extends their lifespan significantly.

What to Do When Your Scissors Need Sharpening

There are a few options when your scissors have lost their edge:

DIY sharpening — Some people use a sharpening stone, a honing rod, or even aluminium foil to touch up their scissors at home. These methods can help in a pinch but rarely restore a truly sharp edge, and done incorrectly they can damage the blade alignment.

Professional sharpening — The best results come from having your scissors professionally sharpened. A professional sharpener uses the correct angle and technique for each type of scissor, restoring the original bevel and producing a clean, lasting edge.

Frequently Asked Questions

Can you sharpen scissors with a serrated edge? Lightly serrated scissors can be sharpened, but heavily serrated blades require specialist equipment. Get in touch if you're unsure about your scissors.

Will sharpening change the way my scissors feel? A good professional sharpen should restore your scissors to how they felt when new — or better. The tension and alignment of the blades shouldn't be affected.

How long will the sharpness last? With proper care — storing your scissors in a case or on a magnetic strip, and not using them on materials they're not designed for — a professional sharpen should last 6–12 months for regular use.

Can I send scissors and knives together? Yes — pack them together in the specialist shipping box we send you.

Don't Put Up With Blunt Scissors Any Longer

If any of the signs above sound familiar, your scissors are overdue a sharpen. It's one of those small things that makes a surprisingly big difference to your day-to-day work — whether you're in the kitchen, the sewing room, or the salon.
