According to a recently published scientific paper, a team of researchers has developed a wood processing technique that makes the material 23 times harder, making it possible to create sharp wooden knives and nails.
Material scientists at the University of Maryland have reportedly developed a type of hardened wood that can be used as a sustainable alternative to materials like steel and ceramics. To demonstrate the toughness of their chemically-treated wood, the team created a knife that is allegedly nearly three times sharper than a stainless-steel dinner table knife, as well as a wooden nail that can be hammered through wood without sustaining any damage, and that isn’t affected by rust.
