🔪 Can you bring Scissors / utility knives on a plane?
Blades under 6cm only (no utility knives)
As of 2026-08-21
The rule in detail
Scissors with a blade of 6cm or less are allowed in the cabin; anything longer has to be checked. Utility knives and box cutters are barred from the cabin regardless of blade length, because a retracted blade can always be pushed back out. Pack sewing, garden and barber scissors in your suitcase from the start, and if you expect to open packaging on the trip, take nail clippers rather than a box cutter.
Why the rule is written this way
It is classified as Allowed with conditions — check the rules because capacity, shape and quantity decide whether it passes, so the same object can be confiscated on one trip and not the next.
Measure it yourself before you leave, and if it is borderline ask the airline and keep the answer in writing. At the checkpoint the final call is the security officer’s.
The rules this verdict comes from
The verdict above follows from 1 Korean rule listed below, named in the original Korean because that is how they are indexed at the national law database. These are the rules themselves, not an airline summary — when screening staff disagree, this is the text that decides. Rules are amended; anything changed after the review date above follows the original.
What actually happens at the airport
- Check-in desk — this is the point of no return for your suitcase. Anything that may only travel in the cabin cannot be retrieved after this step.
- Security screening — if the X-ray flags a shape, the bag is opened. Most problem items are caught here.
- Extra check at the gate — on some routes there is one more inspection.
Confiscated items are rarely returned. If you are unsure, confirm the specification before you leave home.
The 6cm is the blade alone, measured from the pivot — not the overall length of the scissors
