A man who ditched his medication to improve his "physical relationship" with his wife became out of control and assaulted her.
Police alerted to the incident at Pleasant House in Staple Hill spotted David Wilkie clutching three knives.
When they asked him if he was alright, he asked them: "Do I look alright?"
As he approached them he was Tasered to the ground and was arrested.
Wilkie, 41, of Fishponds Road, pleaded guilty to possessing a blade, affray, common assault and criminal damage on June 16.
Judge Martin Picton jailed him for 12 months.
He told Wilkie: "You were seriously out of control.
"You lost all self-control.
"You were violent to your partner, police were alerted and you were aggressive towards them and caused them to fear violence as you approached them with a knife.
"Brandishing of knives towards police is a very serious offence and it calls for serious punishment."
Neil Treharne, prosecuting, told Bristol Crown Court Wilkie's drug habit had caused difficulties in his relationship with his partner.
On the day in question he pawned her phone to pay off a drug debt before coming home appearing to have been drinking and turning violent.
The court heard after threatening to cut himself he threw his partner to the floor and against a wall and grabbed a knife.
When he heard her call a friend, asking the friend to call police, he stabbed the knife into a table and smashed a mug.
He then said: "They're going to have to use brutal force to get me out of here."
Having approached police, armed with blades in both hands, he was Tasered and arrested.
He refused to be interviewed.

Catherine Spedding, defending via video link due to coronavirus pandemic, said: "He was not taking his medication at the relevant time.
"It was affecting the physical relationship with him and his wife.
"He has little recollection of what happened.
"He's extremely sorry and upset regarding the hurt and upset to his wife and attending officers."
The court heard father-of-two Wilkie was back on medication and determined nothing of this sort should happen again.
