Emotions were high after these two assaults and a brawl broke and during the melee, Abbott was stabbed in the abdomen just below his ribs by Rocky Ronaki, he said.
Jenson said security camera footage showed Rocky Ronaki was still holding the knife in his right hand as he and his brother left the bar.
Abbott told the court he was "pretty intoxicated" and so had little recall of events and only realised he had been stabbed when he saw blood pouring from the wound.
Abbott spent four days in Tauranga Hospital and made a full recovery, the court heard.
Rocky Ronaki's lawyer David Bates put it to Abbott that he had instigated the altercation.
Abbott repeatedly refuted the suggestion but said he "probably" threw a few punches to defend himself.
Crown witness Samuel Williamson, a long-term friend of Abbott's, told the court he saw punches being exchanged between one of the accused and Abbott.
He then saw a knife suddenly skid across the smoking room floor and watched the first man's companion pick it up and plunge into Abbott side, Williamson said.
"I saw the knife go in with my own two eyes," Williamson insisted when challenged by one of the defence lawyers he was mistaken.
The trial continues today.
