Head of Marketing & Community at a British anti knife crime charity Steel Warriors Christian d'Ippolito (R) takes part in a social and community training event for "World Pull Up day" organised by Steel Warriors at the calisthenics gym they created by melting the knife blades handed over by the Metropolitan Police, at Finsbury Park, in London, on September 14, 2024. "Our gyms stand as a powerful metaphor... that a negative can be turned into a positive," said Ben Wintour, as he looked at his outdoor London gym made from seized knives. The gym at a park near Brixton, south London, is one of four in the British capital constructed by the "Steel Warriors" charity, which Wintour and co-founder Pia Fontes established in 2017 to help young people avoid knife crime.
