How to Adjust Your Scissor Tension Screw
Adjust your scissor tension screw correctly — the drop test, tools needed and how wrong tension damages expensive blades.
20 April 2026
Incorrect scissor tension causes hand fatigue, edge damage and poor cutting results. The tension screw exists so you can calibrate your scissors to your hand pressure and cutting style. Every UK barber and hairdresser should know how to adjust it properly.
Across the UK, adjust scissor tension screw remains a priority topic for working barbers, salon stylists and apprentices alike. The guidance below reflects professional standards and equipment choices available to British professionals in 2026.
Understanding scissor tension
Tension controls how tightly the blades press together at the pivot. Too loose and hair folds between blades. Too tight and the blades grind together, dulling edges and straining your hand. Correct tension feels smooth with controlled blade movement.
The drop test method
Hold scissors vertically by one finger ring. Open blades to 90 degrees. Release the moving blade. It should fall smoothly and stop around 45 degrees. Stops above 45 degrees: too tight. Falls below 45 or closes fully: too loose.
Perform this test daily before your first client.
Making adjustments
Use the provided tension key or a coin on standard screws. Turn in quarter increments only. Tighten clockwise (typically) to increase tension. Test after each adjustment. Never force a stiff screw — apply penetrating oil and wait.
Record your preferred setting if you share scissors with colleagues.
When tension will not hold
Screws that loosen within hours may indicate worn pivot bearings or damaged bumpers. Professional servicing replaces these components for £20–£40 — far cheaper than new scissors.
Persistent problems on premium professional barber scissors warrant manufacturer contact.
Tension and sharpening relationship
Barbers who sharpen frequently should check tension after each service — sharpening slightly changes blade geometry. SS Nexus includes tension keys with scissor purchases and documents recommended settings per model.
Correct tension extends time between sharpenings noticeably.
