Police are warning about a knife which folds up into the size of a credit card holder.
The credit card knife contains a three inch blade with the ‘credit card’ folding into a handle.
A man got in touch with West Mercia police concerned a young person he knew had purchased the knife.
The knife has been seized but police want to remind people what to look out for and reiterate the dangers of carrying a knife.
They're calling on parents, teachers, carers, even security guards and door staff to be aware of this item and be extra vigilant.
