This is a Samurai sword discovered by police on patrol after hearing reports men were walking the streets with weapons.
Officers were called to Dinas Lane in Huyton yesterday afternoon following concerns about armed thugs in the vicinity.
They arrested two men, aged 20 and 32, and a machete was found.
A vehicle has been seized.
Photographs showed two police cars boxing in a dark coloured car, with one of the officers wearing a face mask during the arrest.
Later, a Samurai sword was found around nearby Jubilee Park.
A Merseyside Police spokesman said: "We will continue to disrupt and deter those involved in serious violent crime."
The action was part of the force's Operation Target, a long-running blitz of serious and violent crime in the county.
The operation also focuses on serious assaults, armed robberies, murder investigations, along with violence in night time economy areas, county lines and drug use.
The force received £4.2m from the Home Office’s £100m Serious Violence fund to boost high-visibility patrols, using hand-held metal detectors and metal detecting gloves, and increasing disruption activity including stop searches, roadside checks and open land searches.
Police in Knowsley have been busy in recent days, and were in action again last night, close to the border with Sefton, when an 18-year-old man was apprehended by one of their trained dogs called Chico.
The teenager was stopped following reports of a motorbike being ridden dangerously around Aintree Lane.
The bike was seized.
Also on Wednesday, in the early hours of the morning, at about 3am, police recovered a Kawasaki which was being ridden anti-socially on Dalry Crescent in Kirkby.
