Knife surrender bins have been making headlines across England, with two recent examples showing the scale of weapons that communities are willing to hand in — and raising questions about what these schemes can realistically achieve.
In the London Borough of Greenwich, bins across Abbey Wood, Eltham, Thamesmead, and Woolwich collected 622 weapons in ten months, including machete-style blades, a sword, a banned zombie knife, and numerous large kitchen knives — all surrendered anonymously, without fear of prosecution. In Lichfield District, Staffordshire, a knife amnesty now in its third year collected 1,958 blades between May 2025 and March 2026, bringing the total since 2023 to 4,458. Collected knives are transported to the British Ironworks Centre to be melted down and recycled.
The numbers are striking. But the evidence on whether knife surrender schemes actually reduce violence is more cautious. The Youth Endowment Fund’s evidence toolkit notes there are very few robust evaluations. Two UK studies — one in London, one in Glasgow — found weapon-related offences declined in the weeks following a scheme, but returned to pre-scheme levels within months. Both schemes were also delivered alongside other interventions, making it difficult to attribute the reductions to the bins alone.
That context matters. YEF suggests these schemes may be most valuable not as standalone violence reduction tools, but as one part of a broader strategy — providing community reassurance, offering a safe disposal route, and complementing education and policing activity. Both the Greenwich and Lichfield approaches reflect that thinking. Greenwich’s initiative sits within a wider violence prevention strategy including youth hubs, Safehaven Superhubs, and school-based education. Lichfield’s is delivered through a sustained partnership between the local council’s Community Safety Team and Staffordshire Police, now three years in.
Healthwatch Greenwich has also made an important point about framing: knife crime is a public health issue, not just a policing one. Stabbings cause severe injuries, long-term disability, psychological trauma, and sustained pressure on emergency services. Removing weapons before they can be used is one preventative lever — alongside addressing the conditions and motivations that lead to carrying in the first place.
