I have every respect for peoples religion / beliefs, but no way should we allow kids to carry these into schools. We have a big enough problem as it is with regards to knife crime and we dont need these to add to the problem.

Like Chip said above really, it only takes one of these knives to fall into the wrong hands and there could be a disaster. I know schools / work places try and and bend over backwards to facilitate religions but something such as this is not acceptable. Safety of the kids is paramount over anything.
