A bladed knuckleduster was found and seized following a stop by the force’s knife crime team.
The specialist officers were out on patrol in Bulwell when a passing car aroused their suspicions.
Believing it could be involved in drug activity, the team pulled the vehicle over in Brook Close.
Small quantities of cannabis were discovered on board following a search around 2.25pm on Tuesday (8 October).
A single finger ring with a curved blade fixed to it was also found by the knife crime team, who duly arrested a suspect.
Mark Bestwick, of Critchley Street, Ilkeston, Derbyshire, was later charged with possessing an offensive weapon in public and possessing a Class B drug.
The 56-year-old has been bailed to appear at Nottingham Magistrates’ Court on 24 October.
Sergeant Matt Daley, of Nottinghamshire Police’s knife crime team, said: “This vehicle stop provided a good reason why our team continues to carry out our daily patrols across the community.
“By being out on the roads, we were able to follow up suspicious behaviour and ultimately take a concealed blade off the streets of Nottingham.
“While we do look to spot other forms of criminality when we’re on shift, such as drug offending, the main purpose of the knife crime team is to take bladed weapons out of harm’s way, so we’re pleased to have done that on this occasion.”
