A zombie knife (also known as a zombie killer knife or zombie slayer knife) is a type of ornate knife or bladed weapon inspired by zombie films and TV series. These knives can range in size and shape, but are legally defined in the UK as having a cutting edge, a serrated edge and images or words (whether on the blade or handle) that suggest that it is to be used for the purpose of violence.[1] Despite being designed for collectors and survivalists, the appearance of zombie knives led to their increasing usage in criminality. In 2016, parts of the United Kingdom made the sale of such knives illegal but with exceptions. In January 2024, the UK Government made the selling of zombie knives illegal without exceptions.
