Four World War I bayonets were among weapons handed into police in Surrey during a five week national knife amnesty which ended last Friday.
Most of the knives handed in to Surrey Police were domestic knives
Knives were handed in at 25 police stations across the county, with 1,351 collected in total.
Almost 1,000 were domestic knives, but items including a samurai sword, a ninja star and a Ghurkha knife were classed as being of specific interest.
Supt John Boshier said each knife handed in was a potential weapon.
He said officers would be actively seeking to target those people who had decided not to make use of the amnesty and were still carrying knives in public.
"People who carry knives think they are protecting themselves.
"In fact, knives are considered offensive weapons and people carrying them risk up to four years in prison," he said.
