A drunk hit two men with a hammer outside a busy city bar in what a judge called an “appalling attack”.
Chronic alcoholic Gary Morley, aged 43, struck the strangers after challenging one to a fight, a court heard.
One of the victims said that he could have been killed in the attack outside Boomerangs in Mutley Plain.
But Morley was so drunk he could not recall the incident nor even explain why he had the hammer, Plymouth Crown Court heard.
Jailing him for 12 months, Judge James Townsend said: “This was a quite appalling attack on two people during which you used a hammer and it is set against your terrible record for the use of violence.”
Morley, of Garden Crescent, West Hoe, pleaded guilty to possession of a hammer as an offensive weapon in public on Saturday August 25.
