Pawel Lupa, 41, of Gleneagles Drive in Kirkby-in-Ashfield killed his partner Aleksandra Mrozik, 47, at their home in July, Nottingham Crown Court heard.
A jury found him guilty of the murder of Ms Mrozik and guilty of the attempted murder of Wojcek Bocek, 32.
Lupa attacked his two victims after an altercation at their flat in a "callous attack", Judge Gregory Dickenson said.
The judge said Lupa had shown a "total disregard" for his partner's fate, adding: "You did not lift a finger to try to help or to comfort Aleksandra (after the attack)."

Lupa's barrister Peter Joyce said all three of the people involved in the argument on 16 July 2016 were "heavy drinkers".
"I've never seen a greater consumption of alcohol in any case," he said.
The court heard that Lupa threw a meat cleaver at Mr Bocek and then used a different knife to stab Ms Mrozik in the chest and through the arm.
She was treated by paramedics in the front garden of their home but died on the way to hospital.
Lupa was sentenced to 12 years for attempted murder and will serve the term concurrently with his murder sentence.
Det Ch Insp Hayley Williams of East Midlands Special Operations Unit said: "Both victims were subjected to frenzied attacks.
"There was blood in every room of the house, on several neighbours' doors as Mr Bocek frantically tried to get help."

The endorsement came after Mr Rajoy's Popular Party (PP) gained the backing of the Ciudadanos ("Citizens") party and tacit support from the Socialists.
Socialist lawmakers are said to have been among the 68 abstentions.
The country had faced the prospect of a third general election inside a year.
But the Socialists forced out their leader, Pedro Sanchez, earlier this month after he rejected abstention.
Mr Rajoy has led a caretaker administration since losing his overall majority in an election last December. A repeat election in June failed to end the impasse but strengthened his hand.
The Socialists (commonly known by their Spanish abbreviation, the PSOE) came second on both occasions, their support eroded by radical leftist newcomers Podemos.
For decades, the PSOE and PP took turns in governing the country on their own but last year the popular vote split four ways - the new centrist Ciudadanos party came fourth.
