My Scout group has a box of these, Which we use on nights and camps.
Check with the leader and whether they allow to bring knives to Scouts.
I know our Scout leader only lets the Scouts bring knives on an evening about 'care and repair' all other times the Scouts will use the groups ones.
As an Explorer leader I let them bring knives and pen knives to camps but they are kept in a locked box unless being used. All other nights they use the groups ones.
