Thirteen guns were handed in to police in Kirklees and Calderdale as part of a successful weapons amnesty.
In all more than 250 weapons were taken off the streets by the West Yorkshire Police in a 10-day campaign.
Police saw 96 guns including pistols, shotguns, air rifles and ammunition surrendered in police stations across West Yorkshire.
Samurai Swords, machetes, axes and crossbow bolts were also surrendered with a total of 162 taken off of the streets.
The breakdown for Kirklees saw six guns and three bladed instruments handed in. And over in Calderdale seven guns and 15 bladed instruments. were given up
The weapons surrender followed a recent change in the law which makes it illegal for certain people to hold antique weapons and is part of a national campaign.
During the 10 days anyone who handed in a weapons could do so without fear of prosecution.
The weapons will now be checked for forensics and either destroyed or donated to The Royal Armouries at Leeds.
Assistant Chief Constable Andy Battle said: “We expected antiques that had perhaps been gathering dust in someone’s attic or so-called ‘trophies of war’ but others have been surrendered too.
“The 10-day surrender gave people the chance to hand in these weapons who, potentially through no fault of their own, were illegally owning them.
“People could hand in the weapons safe in the knowledge that they would not be prosecuted for the illegal ownership of them. The weapons we have handed in will now be tested to ensure they have not been involved in any criminal activity and then securely disposed of.
“Any weapons that are of historical significance will be given to the Royal Armouries museum.”
Mr Battle added: “Every single item handed in is a victory for law abiding citizens as these are weapons that cannot now get into the hands of people who mean others harm.
“I am delighted with the response we had and it was better than we had even hoped for.”
The laws around antique firearms have been tightened which mean that someone who has served or received a criminal sentence can no longer possess an antique gun.
The sentencing guidelines for possession for sale or transfer of an unauthorised firearm or ammunition have also been raised from 10 years to a maximum penalty of life.
