Peter Billy Dean Price, 27, of Broadmoor, Kilgetty, Pembrokeshire, had previously pleaded guilty to inflicting grievous bodily harm when he appeared in the dock for sentencing.
The victim needed a total of 34 stitches to his wounds after being assaulted in the toilets of the bar.
Swansea Crown Court heard Peter Price had no recollection of travelling the more than 50 miles from his home in Pembrokeshire to the bar on Swansea’s Wind Street where he attacked a stranger.
Sending Price to prison a judge said the only reason a person would wear a knuckleduster on a night out was to cause maximum damage if it came to a fight.
Price had five previous convictions for seven offences including two assaults by beating and a GBH.
All these offences had involved him punching his victims in the face, with the GBH from 2021 seeing him sentenced to 19 months in prison suspended for 20 months after breaking a man’s jaw.
Judge Paul Thomas KC said it was clear Price had a savage, uncontrolled temper and had carried out a wholly unprovoked and vicious assault on his victim.
He said the only reason a person would wear a knuckleduster on a night out was to cause ‘maximum damage’ if it came to a fight.
With a one-quarter discount for his guilty plea Price was sentenced to 21 months in prison. He will serve up to half that sentence in custody before being released on licence to serve the remainder in the community.
