The Knife Angel (also referred to as the National Monument Against Violence & Aggression) is a contemporary sculpture formed of 100,000 knives created by artist Alfie Bradley and the British Ironworks Centre, based in Oswestry, England.

Completed in 2018, the structure of the angel stands at 27 ft (8.2 m) tall. In order to create the sculpture, 200 knife banks were produced by the Ironworks and amnesties held for individuals to anonymously donate their knives. Knives seized by police were also included, some of which arrived in evidence tubes still with bodily fluids on their surface.

The sculpture was created in order to highlight knife crime in the United Kingdom and educate young people on the harmful effect violent behaviour can have on their communities.
