You may have had this experience when you were young: you accidentally scratched your skin on the paper when turning the pages of a newly issued book. Sometimes, its not that your skin is too tender, but paper can be as sharp as a razor blade. nadeem haidary took advantage of this property of paper and invented the disposable paper razor. The razor is made of recyclable waterproof paper and does not require additional blades. It can be used after being disassembled. Although this invention is not very practical and cannot replace the daily razor, the concept is novel enough and more products can be derived from this concept in the future.
