I know a few of those people, I mean cowards. The thought of a knife in someones hand instantly transforms it into a machette slicing through the calm peaceable society. The mental disconnect doesnt even make any sense, how does a simple folder useful in all facets of daily life become a weapon of serious destruction? They give you shifty looks until they need to eat some crow and ask you to cut, slice, or pry something for them. Then you get 2 seconds of praise and its right back to you being a savage.
