Paper cut: Can a saw made out of paper slice through wood? - CNET

"While this really doesn't have any practical applications, it was interesting to do," he writes on his site. "Even more so, since the paper I used was nothing out of the ordinary -- just regular printer paper with no special treatment. Add to that the time of year (it was hot and humid, making the paper fairly limp with moisture), it's amazing that it worked at all."

He gave the paper-blade concept a shot at cutting a different surface, but it wasn't happening. "I did make another 'blade' to test it on a piece of aluminum, but it more or less just polished the edge before wearing out." he wrote. "The abrasiveness of the paper works well on wood, but is no match for anything harder."

Many YouTube viewer pointed out that the battle is kind of a Civil War, since paper and wood both come from trees. Still, it's a marvel to watch, and Heisz's video has eaed nearly 2.5 million views after just one day -- and paper has eaed some new fans. Wrote commenter Rom Jaikat, "Thank you, I now have a whole new level of respect for paper."
