Prosecutor Jonathan Sharp said: "The defendant saw him and walked directly up to him with the blade held between thumb and forefinger.
"He then slashed him down the face, causing a deep wound extending from temple to chin.
"He paused for a moment and looked Bridger directly in the eyes, in Bridger's own words 'as if to admire his work or show me who it was'."
The child killer also suffered a cut to his arm as he tried to defend himself.
Bridger needed more than 30 stitches to the face wound, which required surgery under general anaesthetic. He will be scarred for life.
Ferreira and other life prisoners had talked about attacking Bridger to make him reveal the whereabouts of April's body, police were told.
