Knives can be handed in at local police stations during a five week amnesty, said police.
From Monday, August 25, residents across the county are being urged to consider the potentially life-threatening consequences of carrying a knife.
There will be special amnesty bins at 10 designated police stations county-wide, and anyone will be able to anonymously dispose of a weapon, whether it belongs to them, a friend or a relative.
Assistant Chief Constable Mark Bates said: “Carrying a knife in public will not be tolerated by Lancashire Constabulary, and the consequences of doing so are potentially devastating.
Between April 1, 2010 and March 31, 2014 there were 3712 offences involving knives across Lancashire, including 612 offences of possessing an article with a blade or point, 459 knife-related public order offences and 321 woundings.
And while knife crime is falling in Lancashire – down to 845 recorded offences county-wide in 2013 from 1004 in 2011 - officers are keen to stress no one should be armed with a knife on Lancashire’s streets, and the consequences of carrying one could be devastating.
The maximum penalty for an adult found in possession of a knife is four years in prison and a fine of £5000.
The 10 amnesty bins will be accessible 24-hours a day and have been funded by Lancashire’s Police and Crime Commissioner, Clive Grunshaw, using money seized from criminals through the Proceeds of Crime Act (POCA).
The Commissioner said: “I am fully supportive of Lancashire Constabulary’s bid to remove knives from our streets.”
Bins will be available at Morecambe and Lancaster police stations.
The amnesty runs until 8am on September 29.
