A pensioner stabbed his wife in the stomach during a drunken row as he made himself a sandwich, a court heard.
Leslie Corby later told police he had grabbed the weapon and lunged at wife Sharon before she had a chance to attack him.
Leeds Crown Court heard Corby and his partner of 20 years had been to a funeral earlier that day.
Corby, 65, then went to a pub with friends before returning to their flat on Stanley Road, Eastmoor and going to bed.
Prosecutor Heather Gilmour said Mrs Corby continued drinking cans of lager in the flat and the couple had a “tiff” when her husband awoke.
Ms Gilmour, 50, said Corby picked up a knife and stabbed his partner in the stomach.
Mrs Corby did not realise she had been stabbed until she went into the room and sat down.
She lifted her jumper and discovered that she was bleeding profusely.
Ms Gilmour said Corby then went outside to get help. He told a neighbour: “Help me, it’s Sharon - I’ve stabbed her.”
By the time help arrived Corby was sat in a chair telling his wife that he was sorry for what he had done.
Mrs Corby was taken to hospital in Leeds suffering from a cut to the abdomen. Her liver was also damaged from the wound.
Corby was arrested and told the officer they had rowed while was making a sandwich and had grabbed the knife.
He pleaded guilty to unlawful wounding.
Daniel Smith, mitigating, said the couple were now living apart.
Mr Smith added that Corby was in poor health after suffering a stroke.
He was given a 22-month sentence, suspended for two years. Corby was also made the subject of a two-year supervision order.
He was also told he must attend a 50-day programme designed to address his offending.
