A drinker armed himself with a six-inch bladed knife after being attacked in a pub, Lincoln Crown Court was told.
Iain Bainbridge reacted after being hit by another man while he drank in the Grantham pub.
Andrew Scott, prosecuting, said the attacker had been involved in an argument with a woman and as the couple reached Bainbridge’s table the man pushed Bainbridge and then struck him.
Moments later Bainbridge walked into the pub kitchen and armed himself with a six-inch bladed knife before returning to the bar.
Mr Scott said “There is no suggestion he was using the knife in a threatening manner. He said he only intended to frighten the man who had hit him.”
The court was told that no action was taken against the man who sparked the incident by assaulting Bainbridge.
Bainbridge ,52, of Commercial Road, Grantham, admitted possession of a bladed article in a public place on 30 January. He was given an eight month jail sentence suspended for two years and ordered to pay a £100 victim surcharge.
Mark Watson, defending, said “He was the victim. He was being used as a punch bag by this man but he shouldn’t have had the knife and he recognises that.”
