Two boys with Ava White on the night she died were carrying a "Rambo knife", a witness said.
Ava, 12, was stabbed in the neck in Liverpool city centre. A 14-year-old boy, who cannot be named for legal reasons, denies her murder and manslaughter.
Boy A, from South Liverpool, accepts stabbing Ava with a flick knife, but says he "didn't mean to" and was "trying to get her away from me". He has told a jury he thought she was a boy, who might be armed, and feared she was going to "batter" him.
