Machetes, swords and rusty kitchen knives were seized by police as they patrolled train stations and combed potential hiding spots for weapons.
The gruesome blades were recovered during stop searches and land sweeps across Merseyside as part of an operation targeting knife crime.
Officers also carried out secret shopping trips to investigate whether businesses were adhering to guidance around the sale of blades.
Merseyside Police's anti-knife crime initiative, Operation Sceptre, led to 141 stop and searches last week. Fifteen people were arrested on suspicion of possession of a bladed article.
Sixty one knives and swords were found - with pictures released by police revealing that ceremonial blades, machetes and kitchen knives were among the haul.
A total of 121 weapon hunts were also carried out, with search teams examining areas considered as potential hiding spots for weapons
Blades are known to have been stashed in guttering, bushes, alleys and wooded areas by thugs who wish to have quick access to a knife without taking on the risk of carrying one and being caught with it.
The police action took in train stations, including Lime Street, where police said a number of people were arrested over drugs allegations.
The operation coincided with a joint Merseyside and North Wales Police investigation into cross-border drug dealing last week.
That saw a man arrested after he swallowed a bag of what is thought to have been heroin as he fled officers who surprised him at Green Lane station in Birkenhead.
The recovery of the sword was the second seizure of a sword on Merseyside in a matter of days, with one found by officers on Harrowby Road in Birkenhead this week. That blade has been recovered and will be destroyed.
Police said officers also visited to schools to discuss knife crime with pupils and attended almost 400 shops to give advice on the sale of blades and to carry out test purchases.
Superintendent Jenn Wilson said: “Reducing knife crime in Merseyside is an ongoing process, but this dedicated week of action provides all police forces with a platform to shout about the activity they have going on as well as talking to young people, targeting specific areas, seizing a range of knives and putting those carrying weapons behind bars.
“We are working all year round to take weapons off our streets and protect the community.
"This week of action is only a snapshot of what we have going on and I hope that those living in Merseyside feel reassured and know that we will continue seeking out those involved in knife crime, enticing young and vulnerable people to carry weapons or involved in gangs.
“Carrying a knife puts you in significant danger and can lead to fatal consequences, whether this is the intention or not."
