The 23-year-old star was trying to play Five Finger Fillet, in which the players spread their palms and constantly stab the empty spaces between the fingers with a sharp object, reported E! Online.
However, the actor's daring act during the press tour turned frightening when he accidentally stabbed his finger and also damaged a table worth USD 10,000.
Speaking on talk show 'Late Night with Jimmy Fallon', Hemsworth said, "It was the first stop we did on 'The Hunger Games' press tour and I wanted to impress everyone and I'd had a couple of drinks."
Hemsworth said he used to practise the game during his school days.
"I used to do it a lot in science class when I was in high school - I didn't love science class. So I'd sit there in this class and use my pen to do this. You start with a pen and work your way up to a knife," he said.
