35-year-old Kyle Thomas tried to break his victim’s knees with a hammer before pouring bleach over him as he slipped in and out of consciousness.
Swansea Crown Court heard the attack, which took place at his former friend’s Brynamman flat, began with Thomas punching his victim’s head before striking him with a weights bar.
Thomas then tried to use a hammer to break his victim’s knees, before he covering him in bleach while he was in agony on the floor while threatening to cut off his penis with a knife.
He then trashed the flat, stealing the victim’s mobile phone leaving him helpless on the floor and covered in blood.
The victim has since left the country to be with his parents after the attack which left him “broken, traumatised and confused”.
Swansea Crown Court heard that Thomas’ victim had no previous sex offence convictions and there was no evidence or suggestion that he was a paedophile.
Thomas pleaded guilty to grievous bodily harm with intent, criminal damage and theft.
He has previous convictions for GBH with intent, assault occasioning actual bodily harm and batter, including for assaulting his own mother and brother.
Jailing Thomas for eight years and five months, Judge Huw Rees told Thomas: “You attacked your victim mercilessly and you covered him with bleach at one point.
“He was lucky he didn’t suffer life-threatening injuries.
“You left your one-time friend scared witless.”
Thomas was also handed a 15-year restraining order not to contact his victim.
