A man found in possession of this large kitchen knife told police he was trying to sell it.
Thornton Heath Safer Neighbourhood Team officers arrested the man on Tuesday near the Clock Tower.
This is the second knife seized by police around the High Street in less than a week.
Six days ago officers also recovered another knife (pictured) after receiving information while on high visibility proactive patrols as part of Operation Nightingale in Thornton Heath.
The operation is targeting violent crime in and around the High Street.
This comes after two double stabbings in Woodville Road in July and November last year.
