Carry rules for a keychain multitool in the UK

Updated: October 2026

You have seen small, locking, or airline safe on a keyring tool and you want to know whether those words answer the street. They do not. This page is the public-place rule for a bladed or sharply pointed article, and the folding-pocketknife exception inside it. The listings are in the [multi tool key ring comparison](/hub/lawn-and-garden-equipment/multi-tool-key-ring). A stated lock is a shape question on the [one-piece or folding](/hub/lawn-and-garden-equipment/multi-tool-key-ring/sub/multi-tool-key-ring-one-piece-vs-folding) page. Peter F. wrote this on 22 October 2026 from GOV.UK, the legislation, and CPS guidance. This is not legal advice.

The exception is a cutting edge, not the whole tool

GOV.UK's page on buying and carrying knives says it is illegal to carry most knives in public without a good reason. The exception is a folding pocketknife with a cutting edge no longer than 3 inches that is not a lock knife. Three inches is about 76 mm of cutting edge. It is not the length of the whole tool, the handle, or the keyring. A highlight such as 7 cm does not put a folder inside the exception. Seven centimetres is 70 mm. If that figure is the whole tool, you still do not know the cutting edge, and you have not answered the lock. Good reason is for a court. The examples include work, religious reasons, and national costume.

Three UK texts, not one slogan

England and Wales use section 139 of the Criminal Justice Act 1988: a bladed or sharply pointed article in a public place without good reason or lawful authority. GOV.UK states the maximum for an adult as 4 years, an unlimited fine, or both. Scotland uses section 49 of the Criminal Law (Consolidation) (Scotland) Act 1995. The exemption is a cutting edge of no more than 3 inches, also printed as 7.62 cm, and the stated maxima are 12 months on summary conviction and 5 years on indictment. Northern Ireland has its own text of section 139. Do not copy the England and Wales maximum across. CPS guidance treats a lock-knife as outside the folding exception. A screwdriver is not, by itself, a bladed article, and that does not classify a box-cutter edge.

What these listings actually state

The Shard lists no blade and no lock. The DoohicKey lists a box cutter and no lock. A fixed notch is not a folding pocketknife, so do not pin the 3-inch exception to that plate. This page will not call a plate lawful or unlawful. The Moineefo, at about £9.48, states a fold-out blade and secure locking positions, with no reviews. The 7 cm highlight is the whole tool, not a measured cutting edge. A stated lock sits outside the exception GOV.UK describes. A knife mentioned only in a GOWEILE or Uadme review is not a measured cutting edge. The buying guide is where you decide you did not want a blade.

The street is not the cabin

GOV.UK's work-tools list puts screwdrivers and wrenches in the hold. The CAA's sharps guidance tells you to pack multi-tools in the hold as well. Airline safe, and TSA approved on the Lever Gear listing, are seller or writer copy. The bottle and screw sequence, without opening a blade, is the how to use page.

Common questions

Does smaller than 3 inches overall put a tool inside the exception?
No. The exception GOV.UK describes is a folding pocketknife whose cutting edge is no longer than 3 inches, and which does not lock. The length of the handle, the key, or a 7 cm tool highlight is a different number. A 7 cm overall length can hide a shorter edge, or it can be the whole object with no edge measured at all.
What does a stated lock do to that exception?
It takes the knife outside it. CPS guidance treats a lock-knife as not immediately foldable, which is the point of the exception. In this folder the Moineefo listing states secure locking positions and a fold-out blade. That is enough to stop treating the exception as if it applied. It is not a verdict on a particular pocket or a particular day.
Is a flat screwdriver a bladed article by itself?
CPS guidance says a screwdriver is not itself a bladed article. A Shard-style flat driver can sit in that sentence. A box-cutter edge, a sharp point, or a fold-out blade is a different question, and this page does not fold those into the screwdriver line. A forum line that says not a knife is not the same as nothing in this tool is pointed.
Does the same 3-inch idea appear in Scotland?
Yes, in section 49, which prints both 3 inches and 7.62 cm for the folding-pocketknife exemption. The offence is the Scottish one, with its own maxima: 12 months on summary conviction and 5 years on indictment, as the text states. Reasonable excuse is the Scottish wording. Do not paste the England and Wales 4-year maximum onto a Scottish charge.
Does airline safe answer the street question?
No. Street carry is section 139 or section 49. The cabin is a separate restriction, and GOV.UK already puts screwdrivers in the hold. A TSA line on a listing is United States airport language on a UK product page. It does not decide a public place in Britain, and it does not decide a UK departure gate.
Where does the Moineefo listing sit?
It states a fold-out blade and locking positions, weighs in at a 15 g item-weight field, and has no reviews in the saved listing. The 7 cm line is the whole tool. Those facts put it outside the non-locking exception as described, and they leave the cutting-edge length unmeasured. We do not call the product illegal. We say you should not buy the exception along with it.
