Unbelievably true, paper blades cut plastic and wood

The paper is fragile, completely harmless, how can it be able to cut quite hard and durable materials like plastic and wood?

An American craftsman, Johnny Q, turned an A4 paper that looked "soft" into a knife-like hand tool. He cut a square piece of paper and stuck it on the paper to double the thickness of the paper. Then, cut a perfect circle with the chopper cutter and replace it into the door edge of a cutter. Although it cannot be as hard as a saw blade, it can completely cut through cardboard, perpspex glass panels are made of acrylic, plastic and even wood.
