The weapons were seized as part of Operation Jemlock.
The operation was launched in April 2019 in a bid to tackle serious violent crime in the region.
Over 5,600 arrests have been made since, with 739 weapons seized and 11,599 pieces of intelligence submitted.
West Yorkshire Police tweeted: "Officers from @WYP_OpJemlock continue to make a difference in the communities of West Yorkshire.
"Here are some of the weapons they seized last week.
"Since the operation began officers have made over 5600 arrests, seized 739 weapons and submitted 11599 pieces of intelligence."
The Yorkshire Evening Post’s Saving Lives After Lockdown campaign is shining a light on the impact of knife crime across the city, looking at ways to prevent an upsurge in incidents as restrictions are eased.
Superintendent Damon Solley leads Operation Jemock and in April, he told the YEP that it is vital that parents and teachers listen out for signs that young people are involved in gang activity.
Supt Solley said: “Everybody has a part to play to look for the signs that young people are being drawn into that particular life.
“It’s a collective effort on the part of the whole entire community to prevent young people from picking up a weapon in the first place.
“That’s the only way that we’re going to see long term reductions in incidents of violence like this.”
