If you follow the link provided in the first post you can seen the knife being described as "10-inch bread knife". That is not a knife to butter bread with (though it could be done) and contrary to what some have written it is designed to cut.

McGrath's citation of the Nuremberg principles is completely out of proportion and they do not apply here at all. If obeying the rules/orders is a crime you may not obey them without being criminal yourself. But here following the rules is just silly and following silly orders/rules is not a crime. If there would not be a very big difference still between silly behaviour and criminal behaviour the prisons would have to be closed for overcrowding.
