Sometimes, you may need to break paper or something. Tear it by hand, which is laborious and not clean; buy a shredder, which is too expensive and there is not so much paper to break. It would be much more convenient to have shredded paper scissors. It is simple, convenient, cheap and easy to carry. If you really can't buy it, you can buy four scissors and make one yourself.: -).

This is exactly what is missing in life is not opportunities, but discoveries and flashes of inspiration.
