Border authorities in the United Kingdom have reported a significant increase in the seizure of illegal knives at the country's borders, with campaigners warning that the quantities intercepted might represent only a portion of the total imports. In the first half of 2026, Border Force officers confiscated 2,729 illegal knives, including zombie knives, machetes, butterfly knives, disguised blades, and other prohibited weapons, averaging approximately 15 seizures per day. This figure nearly matches the total of 2,912 illegal knives seized throughout 2025. Alongside these, 1,342 other offensive weapons were also intercepted during the same period.
The surge in illegal knife imports is attributed primarily to overseas manufacturers and the widespread availability of these weapons via online marketplaces, often sold through third-party sellers. Experts and advocacy groups highlight the ease of purchasing such knives online, their low cost, and aggressive marketing strategies targeting younger demographics. Social media platforms have also been noted for glamorizing knife carrying, frequently portraying weapons as symbols of status or protection, despite the associated risks.
Political responses to the issue have seen calls for intensified enforcement and new measures to curb online sales. The Conservative Party has pledged to "triple stop and search" efforts and increase policing in areas heavily affected by knife crime if returned to power. Meanwhile, Reform UK has urged more decisive action against the online marketplaces driving this trade, emphasizing that those involved in importing, selling, and possessing illegal weapons currently face insufficient consequences.
The government has introduced legislative measures under the Crime and Policing Act 2026, which criminalizes the sale and possession of zombie knives and similar prohibited weapons, carrying penalties of up to two years imprisonment. The act also empowers police to issue content removal notices compelling social media companies, online marketplaces, and search engines to eliminate unlawful knife-related content or face penalties against both companies and senior executives. Furthermore, the government has allocated £2 million in funding to the National Knife Crime Centre, which coordinates investigations into illicit online weapon sales and works with industry regulators such as Ofcom and Trading Standards.
Despite these efforts, concerns remain over the scale of the problem. Patrick Green, chief executive of the Ben Kinsella Trust, a charity founded after the stabbing death of 16-year-old Ben Kinsella in 2008, expressed alarm at the growing number of illegal knives seized at the border and underscored the ongoing demand for such weapons. The trust emphasized the danger posed by zombie knives and similar blades, which are designed to cause serious injury or death, and highlighted the uncertainty over how many weapons evade detection.
A notable example illustrating the extent of this trade involved Jonathan Soares, a 20-year-old from South London. Soares, a security guard, was arrested in June on multiple charges including fraudulent evasion of prohibitions relating to zombie knives, push daggers, Rambo knives, and stun guns. Investigations revealed he imported these weapons in bulk from countries such as Pakistan, South Korea, and China and sold them online, including to school-aged buyers. Shipments intercepted by police contained large quantities of these blades, with Soares also reportedly considering manufacturing weapons via 3D printing. He is currently awaiting sentencing at Inner London Crown Court.
Police figures indicate that in London, approximately one in ten serious violent incidents involving individuals under 25 years of age this year involved a zombie knife, underscoring the public safety risks posed by these weapons. While government data cites an 11% reduction in knife crime and a 26% decrease in knife homicides since the general election, critics argue further action is needed to stem the tide of illegal knives entering the country and reaching communities.
Authorities and advocacy groups stress the importance of continued enforcement and legislative action to disrupt supply chains and online sales channels, while also tackling the socio-cultural factors contributing to knife carrying among young people. The ongoing debate focuses on balancing enforcement measures with prevention and education to address the complex issue of knife crime in the UK.
