According to the 2026 UK government and CAA (Civil Aviation Authority) guidelines, you can take scissors in your hand luggage provided the blades are no longer than 6cm (2.4 inches) from the fulcrum (the point where the blades cross). Scissors with rounded or blunt ends are also generally permitted regardless of length, though the 6cm rule is the standard for pointed craft or nail scissors. Any scissors with blades longer than 6cm must be packed in your hold luggage (checked bags). It is important to note that even if they meet the length requirement, security officers at UK airports like Heathrow or Gatwick have the final discretion; if they deem an item to be potentially dangerous or if the scissors are part of a larger multi-tool that includes a knife, they may still be confiscated. For 2026 travelers, it is often safer to carry small, folding "travel scissors" or dedicated nail nippers to avoid any ambiguity during the screening process.
