A serrated combat knife was among the deadly weapons handed in to police during a knife amnesty in Rushmoor in Hampshire.
The amnesty began last week - one week after four men were sentenced to a combined 92 years for the murder of Richard Hardy.
Hardy, who was 25, was stabbed to death in Farnborough earlier this year.
Two amnesty bins were placed in Farnborough and Aldershot as part of a police campaign to reduce knife crime in the areas.
Eighteen blades in total have been handed in. Police say the campaign could help save lives
