Does this make paper a weapon?
Turns out the secret to a shockingly sharp paper blade is just to spin it really, really fast. Props to the creative John Heisz for this surprising table saw mod. Even though you'd think it would bounce right off, a single piece of printing paper slices through paper, cardboard, and even balsa wood like it's butter! Only halfway into a thick piece of plywood does the paper blade call it quits.
