"Basically this is what you get when you mix a stapler and a hole punch together,but unlike a hole punch there is no confetti or waste. It makes an arrow type of hole, then feeds it back around itself to hold the document together. I have seen these used at conferences that I have gone to, where hundreds of reading material are handed out. I have also seen these used in the officefor meetings and bookkeeping. Since I am teaching English here in Japan I have also seen these used in schools!"
