MOST children his age finish homework after school — but the world’s youngest knife thrower Grennan Bartlett-Nealeigh throws blades at his little sister.

    The pint-sized performer, aged 9, sends knives rotating through the air towards a target next to 7-year-old sister Charlotte.

    Grennan’s terrifying antics have even seen him perform on “America’s Got Talent” where he was given rave reviews and four “Yes” votes by judges including Spice Girl Mel B and supermodel Heidi Klum.

    The pair, from Dayton in Ohio, the U.S., practice their routine every day which is overseen by their dad Thomas who runs a traveling show called Freakshow Deluxe.

    Grennan, who grew up around freakshow acts, has been practicing various routines since he was a 3-year-old.

    He said: “I used to watch the performers at the freakshow and decided I wanted to try it.

    “I like throwing sharp things at my sister — when we’re on stage and get a lot of applause we like it.”

    Fearless Charlotte added, “I’m not scared because I trust Grennan — he throws really well.”

    Grennan and Charlotte currently perform once a month but during spring and summer they perform up to three times a day.

    They are both paid for their performances and as well as knife-throwing they perform other routines such as glass walking.

    Mom Alice said, “I’m a mom so of course I’m nervous when they do the tricks.

    “But I have total trust in Thomas — I see how great he is as a teacher and I know the kids have total trust in him.

    “As weird as this sounds I’d be more nervous if Grennan were to play American football or Charlotte was to become a cheerleader.

    “There are so many severe injuries that happen every day in regular sports.

    “I feel they’re much safer with us both watching them and guiding them. I am very proud.”
