The company, called Concentrate, says the pencils look like they have already been chewed making pupils less likely to put them in their mouths.
And they say this is a cheap but effective way of encouraging youngsters to get their teeth into their lessons instead.
Concentrate specialises in products to help kids at school and identify why they get distracted or are unable to focus in class, claim the chewed end encourages them to get thinking straight away.
"We know it's daft but just get down to some concentrated thinking and who knows what might happen," said company boss Mark Champkins.
"We began to look at the reasons that children might be distracted, uncomfortable or unable to focus in lessons - and we set about designing some simple, cost-effective products to address some of the problems." (roundup)
