A crown court in the city of Leicester found Jason Moore guilty of attacking John-Paul Skamarski last August. The presiding judge chastised Moore for taking his obsession with the "Nightmare on Elm Street" killer too far, the BBC reported.
"What you were fascinated with was using that glove to kill someone," Judge Michael Pert said as he handed down a life sentence. "The person you chose was your friend who was asleep and had no reason to expect an attack."
Moore will have to serve at least 54 months of his sentence.
Detective Sgt. Gary Rogers of the Leicestershire Police told the BBC a "lot of skill" went into the creation of Moore's weapon.
"I have seen some horrific weapons in my life and that is probably the most horrific I have seen," he said.
