My longest is a 31" blade sword and the tiniest is a 1/2 - 3/4" blade gum machine folder I have left from my childhood. Can you imagine it being politically correct having knives dispensed to kids for a penny from a gum machine? They weren't sharp of course, but you could rub 'em on the sidewalk so if you tried real hard you might cut string! I'll post a pic later. I have to go dig it out of my knife box.
