The seven-year-old boy had smuggled the knife into school down his trousers.
But one student who had been intimidated was so frightened that he broke his silence and told his teacher.
Staff at Sinclair Primary School in Southampton, Hampshire, immediately stepped in and the boy was excluded.
The circumstances of the incident were being investigated by the authorities.
Head teacher Gerida Montague also informed the parents of all 195 pupils at the school for four to 11-year-olds.
Pupils have been offered specialist counselling to help them deal with any trauma they may have suffered.
It is believed the boy intended to use the knife to vandalise property. He has now been withdrawn from school.
Mrs Montague said child safety is the school's 'top priority', and appropriate action was taken straight away after the incident, which happened on April 28. Read More
