An ambulance was called to the scene and the man was taken to hospital for a non-life threatening injury. He has now been discharged.
CCTV and witness enquiries into the incident are ongoing and anyone with any information is urged to contact police.
Detective Inspector Ben Dyer said: “We are investigating an attack on Lodge Lane last week which left a man injured, fortunately not more seriously.
“Knife crime has no place in our communities. If you saw this incident, captured anything or have heard information since, we want to hear from you now.
“Similarly, if you were driving along Lodge Lane on Friday afternoon and have dashcam footage then please review it and if you see anything let us know.
“We rely on members of the public coming forward with information about such incidents to keep our streets safer.
“Please pass on any information you have and we’ll take positive action to remove those who use weapons to cause fear and harm in our communities from our streets.”
