Can You Buy a Knife in the UK? Rules You Must Know

Purchasing a knife in the UK is legal, but it comes with strict legal boundaries. Whether you're a hobbyist collector, professional chef, or outdoor enthusiast, understanding the rules around knife ownership is essential. This guide will walk you through what’s allowed, what’s not, and how platforms like KnifeMarket help you find quality knives while staying compliant with UK laws.

Legal Knife Purchases in the UK

Yes, you can legally purchase a knife in the UK. However, UK knife law is tightly regulated to prevent misuse. The focus is on safety and clear intent of use. Here's what you need to know:

Age Restrictions

In England and Wales, you must be at least 18 years old to buy most knives. In Scotland, individuals aged 16 or 17 can legally buy kitchen knives and cutlery.

Types of Knives You Can Legally Buy

Folding pocket knives are legal to purchase if the blade is non-locking and under 3 inches (7.62 cm) long. Fixed-blade knives are also legal when bought for legitimate purposes such as cooking, camping, or work-related tasks. Machetes can be purchased by anyone over 18 and are typically used in gardening, agriculture, or forestry.

Carrying Knives in Public

In general, carrying knives in public is illegal unless you have a valid reason. Folding pocket knives that are non-locking and have a blade length under 3 inches can be carried without justification. Other types of knives may be carried if you have a valid reason, such as using them for work (like a chef's knife), for religious purposes (such as a Sikh kirpan), or as part of a national costume.

Prohibited Knives

Certain knives are completely banned in the UK, meaning you cannot sell, buy, possess, or import them. These include flick knives (also known as switchblades), gravity knives, butterfly knives (balisongs), and disguised knives that are hidden in everyday objects like pens or combs. Zombie knives, which feature a cutting edge, a serrated edge, and any imagery or wording suggesting violent use, are also banned. Stealth knives made of non-metallic materials not intended for food, home, or toy use are prohibited as well. Additionally, swords with curved blades over 50 cm in length are not allowed.
