Police arrest 14 people during knife campaign
The force said knives were surrendered in amnesty bins at police stations in Bournemouth, Poole and Weymouth.
It carried out eight weapons sweeps and four stop-and-searches, as well as giving presentations to pupils in 19 schools.
Dorset Police and Crime Commissioner David Sidwick said the county had the second lowest rate of knife crime across England and Wales.
He said the new wands, high-visibility patrols and “powerful education” demonstrated the force’s commitment to reducing knife crime further.
Ch Supt Heather Dixey said: “Some young people carry a knife because they think it will make them safer, but carrying a knife can actually make them more vulnerable.
“We have been very proactive in providing education and engagement opportunities to local schools and discussing these common misconceptions.”
