"Last year, a group of researchers announced they had developed wood that they say is 23 times harder than its natural counterpart. They used the hardened wood to make a table knife that their study shows is nearly three times sharper than commercial table knives, like those made from steel, plastic and natural wood...To create the hardened wood, researchers used a process involving a chemical treatment, water rinsing, and both cold and hot presses on basswood. They then soaked it in food-grade mineral oil to increase its water resistance and carved the material into knives."
