A zombie knife is a type of bladed weapon that has been increasingly linked to violent crimes and gang use. They are inspired by zombie films and often have an ornate design, with images or words on the blade or handle that suggest it is intended for violence. Zombie knives can range in size and shape, but are commonly defined as having a cutting edge and a serrated edge. Despite being designed for collectors and survivalists, the appearance of zombie knives led to their increasing usage in criminality. In 2018, parts of the United Kingdom made possession of such knives illegal.
