A bin for people to drop dangerous blades into has been set up inside Haverhill Police Station.
It's part of a year-long amnesty to get knives, machetes and daggers off streets in Suffolk.
Over the last six weeks, almost 1,000 have already been dropped off in similar bins at nearby police stations.
As part of the campaign, extra officers are patrolling Suffolk's towns and cities specifically searching for people with knives on them.
A commercial about the campaign is also running on local TV.
