A young woman fought for her life after being attacked by knife-wielding killer Nicola Edgington.
Kerry Clark, now 24, grabbed the blade with one hand and kicked Edgington off her after being attacked in the street.
Miss Clark was waiting at a bus stop when Edgington attacked her before going on to kill grandmother Sally Hodkin, 58.
Edgington bought a knife at a local supermarket and pinned Miss Clark to the ground pointing the knife at her chest.
She told the Old Bailey: "We were grappling. I managed to grab the blade with one hand and kick her off me. It happened very quickly."
Miss Clark, an artist, said she had been listening to music on her headphones at the bus stop when she became aware of a woman approaching her aggressively.
She said: "I saw a woman lunging at me with a knife. She had a knife in her hand and was angling it towards my chest in a downwards motion.
"She was screaming 'You f****** bitch, you f****** bitch'.
"My instant reaction was to put my hand up and try to protect myself from the knife.
"I had the blade in my right hand but I felt her pushing more with the knife, so I went back to try to avoid it.
"I fell to the floor and she was on top of me. I had to fight her off.
"I was looking at the knife. I have a vague recollection of her face which was aggressive.
"She was on top of me with the knife still at my chest. I still had my hand round the blade. I was trying to get her off me or get the knife from her.
"I kicked out at her whilst I was on the ground. As soon as she was away from me I got up. I had the knife.
"I said 'What's wrong with you, you crazy bitch?' She said 'I am not the crazy one. You are the one with the knife in your hand'.
"She appeared angry. She asked for her knife back. I told her to get away, she is not going to have it back. She looked bewildered. She just left."
As people in the street and an estate agent went to help her, Miss Clark noticed she had cuts to her palm and three fingertips from where she grabbed the weapon.
