In the United Kingdom, there are certain restrictions on kitchen knives as part of efforts to control and reduce knife-related crimes. The following types of kitchen knives are generally considered illegal or highly regulated in the UK:
Butterfly knives (also known as balisongs): These are folding knives with two handles that rotate around the blade. They are illegal to import, sell, hire, lend, or give away in the UK.
Flick knives (also known as switchblades): These are knives with blades that can be quickly released from the handle with the push of a button, a spring, or a mechanism. Possessing, manufacturing, selling, importing, or lending flick knives is illegal in the UK.
Gravity knives: These are knives with blades that are released by the force of gravity or centrifugal force when the knife is pointed downward. Possessing, manufacturing, selling, importing, or lending gravity knives is illegal in the UK.
Disguised knives: Knives that are designed to look like other objects, such as pens, combs, or keys, are considered illegal in the UK.
Stealth knives: These are knives that are undetectable by metal detectors or X-ray machines. Possessing, manufacturing, selling, importing, or lending stealth knives is illegal in the UK.
Push daggers: These are knives with a blade that protrudes from the handle and is designed to be held in a clenched fist. Possessing, manufacturing, selling, importing, or lending push daggers is illegal in the UK.
It's important to note that this list is not exhaustive, and the UK's laws regarding knives are subject to change. If you have specific concerns or questions about a particular type of knife, it's recommended to consult the UK government's official guidelines or seek legal advice to ensure compliance with the current laws.
