Actress Brooke Kinsella has called for knife crime awareness to be part of the national curriculum.
The former EastEnders star - whose 16-year-old brother Ben was stabbed to death in 2008 - said she thought the most effective way of tackling the issue was through the classroom.
Writing in the Mail on Sunday, she said: "I am now hoping to set up a conference with as many head teachers as possible to persuade them to begin crime awareness and prevention lessons.
"I hope the message will be part of the national curriculum."
Ms Kinsella began working with the Tories before the election on knife crime, and spent July and August talking to project leaders and community workers about the issue.
The actress said: "Many of the young people I met have no idea of how serious carrying a knife is. They don't realise how easy it is to die from a stab wound.
"Most of the kids out there are basically good and would be better with a bit of guidance.
"In the long term...I am convinced that the most effective way of tackling the problem is in the classroom.
"Although projects often volunteer to hold workshops in schools, the schools themselves are reluctant because they're worried about sending out the wrong message that knife crime is a problem among their pupils."
Her brother died on June 29 after a fight in a bar spilled out on to the streets in Islington, north London. He had been celebrating the end of his GCSEs.
