Didn't the kiwamijapan youtube guy figure out how to do this years ago? Really even then, it's not a new concept. Inmates in prisons turn toilet paper into daggers and I'm sure there are antiquities of sharp objects made from wood and other materials. I don't really understand the significance or newsworthiness of this.
