Kiel Tetley, 34, left the man with serious injuries to his neck, back and head, when he carried out the vicious attack at the Mill House Caravan Site in Doncaster on September 19, 2020.
The 36-year-old victim was left needing urgent hospital treatment after police found him in the Keyworth Close area.
Sheffield Crown Court also heard how police had received a call from a woman earlier the same day saying that Tetley, formerly of Bowness Drive, Doncaster, had threatened to burn the caravan site - where he was a resident - down.
Tetley previously pleaded guilty to the Section 18 assault and threatening to cause damage at an earlier hearing.
He appeared at Sheffield Crown Court on Monday and was jailed for six years.
PC Leanne Daffern, of South Yorkshire Police, said: "Tetley is now behind bars for a serious assault against another man and for making threats that caused a lot of fear and distress.
“His behaviour was clearly dangerous and showed little to no regard for the safety of others at the caravan site, and I am pleased he has admitted his guilt.
“We arrested Tetley from the caravan site that day and worked swiftly to gather the evidence we needed to bring him before the courts. I hope the community is reassured by the quick and positive action taken to put him behind bars.”
