When this master couldn't cut a water bottle, he told his disciple to sharpen his knife. But since the disciple was young, he had no idea how sharp the blade needed to be. So without knowing when to stop, he kept grinding it on different kinds of stones. And finally, the knife became so sharp it could slice right through a sheet of paper. So when it was tested on the water bottle again, it cut through in a single strike. cradit:(@NoxJackson ) on yt
