A 12-year-old girl who attacked a classmate with a razorblade leaving her needing 30 stitches has told a court she did not mean to cut her so badly.
Pictures of the teenager's injuries were shown to the jury
Shanni Naylor, now 13, was attacked in October 2005 while in class at a Sheffield school.
A teacher earlier told the trial she had seen Shanni punching the defendant a number of times the previous day.
At Sheffield Crown Court, the accused, also now 13, denies wounding with intent to cause grievous bodily harm.
Giving evidence, she was asked by Jeremy Baker QC, defending, how she felt about what she had done.
She replied: "It's wrong and no good."
Mr Baker also asked her: "Did you mean to cut her so badly as that?"
'Scratched' with blade
The girl said she was sorry for the attack on her classmate.
When the girl was asked what she did when she approached Shanni in class with a blade in full view of a teacher, the teenager said: "I scratched her with the blade."
She said: "I meant to show her if you come to me again I would do that, I would use this."
The girl said she wanted to put the blade close to Shanni's face to scare her.
A teacher, who has worked at the school for more than 30 years, said more than 100 children were watching the first incident between the two girls when the accused was attacked by Shanni.
She described the incident as "horrendous" and "vicious" and said Shanni was repeatedly punching the defendant's head so it was banging against a wall.
The court heard how the girl, who was also 12 at the time of the incident in October last year, does not dispute causing Shanni's injuries but at issue is the nature of any intent involved.
The trial continues.
