A Coatbridge thug threatened his mum with a knife and went on to hit a cop with a hammer and attack two men with a broken bottle.
Sam McTaggart, 20, was locked up for 34 months at Airdrie Sheriff Court.
He admitted assaulting his mum at her Coatbridge home, and two police officers trying to arrest him on March 2 last year.
McTaggart brandished a knife, threatened his mum, seized her by the throat and shoved her.
He also admitted swinging a blade and a hammer repeatedly at one police officer, striking him a body blow with the hammer.
McTaggart further admitted making repeated attempts to strike a second officer with the hammer.
Defence agent Simon Gilmour said his client had been misusing alcohol and cannabis at the time.
The lawyer added: "His mother had concerns that cannabis use was affecting his behaviour. She confronted him about his lifestyle choices and he acted in the manner described.
"He's been on remand and she has visited him. They are trying to mend their relationship."
McTaggart also admitted illegal possession of scissors in Gartsherrie Road, Coatbridge, on April 19 last year while on bail and threatening or abusive behaviour towards the police on that occasion.
Mr Gilmour said his client had been using the scissors to cut cannabis and had "no intention" of using them as a weapon.
McTaggart further admitted striking two men repeatedly on the body with a broken bottle to their severe injury in Coatbridge on August 9 last year.
One male was attacked in Bank Street while the other was assaulted in Langloan Street.
His lawyer said McTaggart was intoxicated at the time.
Passing sentence, Sheriff Derek O'Carroll told McTaggart: "I take account of the fact that you have a difficult and troubled background.
"Nonetheless, this catalogue of crimes to which you have pleaded guilty includes some very serious offences."
The sheriff said he would have imposed a longer sentence but for the accused's young age and his guilty pleas.
The 34-month stretch was backdated as McTaggart has been in custody since August last year. He will be supervised for a year on his release.
The sheriff explained: "That will provide you with support and assistance, and will also let the court keep any eye on you."
