You can feel it the moment a pair goes dull: hair starts folding, your thumb aches, and suddenly that clean bob is dragging. Nip it early and you save the cut, your wrist, and your sharpening budget. Here is how to diagnose blunt blades on the fly, rescue them if it is a quick fix, and know when it is time to hand them to a pro.

The 90-second dullness triage
Before you panic-call the sharpener, run this quick sequence. It separates a dirty pivot from a genuinely blunt edge and buys you time mid-shift.
| Step | What to check | Decision |
|---|---|---|
| 1. Visual scan | Hold blades under your salon ring light. Any bright glint on the edge or tip? | Glint = flat spot → swap shears |
| 2. Drop test | Open to 90°, lift the thumb blade and let it fall. | Falls halfway = tension good. Slams or stalls = adjust first |
| 3. Tissue test | Lightly snip clean tissue or neck strip. | Fold = dull edge. Clean slice = keep cutting |
| 4. Pivot clean | Wipe pivot with isopropyl alcohol and re-oil. | Grit on cloth = you removed the issue |
Fair dinkum reminder: tension solves half the “my scissors are blunt” complaints. Only book the sharpener once you have cleaned, oiled, and re-tested.
1. Hair folds or pushes away
- What you will feel: Dry sections refuse to slice, fringes feather out, and you need extra tension to finish a perimeter.
- Quick check: Try a clean piece of tissue or a cutting collar. If it folds instead of snipping, the edge is dull.
- Action: Clean, oil, and drop-test. If it still folds, book the sharpener.
2. Grinding, squeaking, or crunching sounds
- What you will hear: A gritty scrape near the pivot or a squeak every time you close.
- Quick check: Open the blades and inspect the inner edge. Any shiny flat patch means the edges are rubbing.
- Action: Clean debris, oil the pivot, and adjust tension. Noise still there? Edge has worn or alignment is off—time for a service.
3. You are squeezing harder to cut
- What you will feel: Thumb fatigue, tight forearm, or clients noticing you fighting through the section.
- Quick check: Drop test. Hold blades at 90 degrees, lift the thumb handle, and let it fall. If it slams shut or barely moves, tension is wrong.
- Action: Reset tension, oil, and test on damp tissue. Persistent stiffness equals dull or misaligned blades.
4. Shiny nicks or flat spots on the edge
- What you will see: Under bright salon light, the cutting edge flashes back at you. That glint is a flat spot.
- Action: Stop using that pair immediately. Micro-nicks snag hair and create split ends. Flag it for sharpening and switch to your backup.
5. You dropped them—no matter how soft the landing
- What happens: Even a short fall can bend the tip or knock the pivot out of alignment.
- Emergency drill: Clean, dry, tension-check, then test on a clean strand. If you feel any catch, send them out. Better safe than a chewed section on a paying client.
Rescue drill before you call the tech
- Clean: Spray with isopropyl alcohol, wipe, and dry so you are not grinding product into the edge.
- Tension: Run the drop test and adjust until it closes two thirds smoothly.
- Oil: One drop, open and close ten times, wipe excess.
- Test: Snip clean tissue or the ends of a wig. Still snagging? Call your sharpener.
Sharpening schedule cheat sheet
| Cutting style | Sharpening frequency | Why |
|---|---|---|
| Wet cutting majority | Every 10-12 months | Moisture is gentler on edges |
| Dry cutting / slide heavy | Every 6-8 months | Dry friction wears edges faster |
| Barber scissor-over-comb | Every 8-9 months | Constant comb contact dials edges down |
| Apprentice / shared shears | Every 6 months | Technique inconsistencies accelerate dulling |
Choosing the right sharpener in Australia
- Ask for convex credentials: Japanese shears need waterstone or specialised systems—not belt grinders.
- Check turnaround and loan pairs: Busy stylists cannot wait two weeks. Many reputable techs offer 24-48 hour turnaround or loaners.
- Look for reviews from stylists, not just barbers: Different edges, different needs.
- Keep the receipts: Warranties (Hikari, Fuji, Joewell) rely on proof of professional servicing.
Keep your edges happier between services
- Wipe, disinfect, and oil daily (follow the cleaning routine).
- Cushion your trolley with a rubber mat to stop accidental knocks.
- Store upright or in padded rolls; never loose in a drawer with clips.
- Rotate pairs: allow your primary scissors to rest while the backups cover chemical services.
- Schedule a quick technique refresher via BehindTheChair.com when you or apprentices slip into bad habits—solid mechanics extend the time between sharpenings.
When to retire a pair
- Blades ground so often they are noticeably slimmer.
- Permanent hinge wobble even after servicing.
- Steel is pitted or rusted near the edge.
- You have “sharpened to death”—if the maker says there is nothing left to hone, retire them and repurpose as mannequin shears.

Build an in-salon first aid kit
Keep a small “shear triage” pouch in your trolley so you do not waste time hunting for supplies mid-appointment.
- 70% isopropyl alcohol spray
- Lint-free microfiber cloth
- Pivot oil with needle applicator
- Mini screwdriver or tension key for your brand
- Soft toothbrush for tooth blades
- Maintenance log card (note cleanings, drops, tension tweaks)
Log each dullness scare in that card, then copy the highlights into your ScissorPedia maintenance log. If you are booking services more than twice a year, the data helps you justify new steel or extra training for apprentices using your premium pair.
