Paragraph 1
In the future, the world's
may be using wooden knives. This may seem somewhat
, but scientists have created a wooden knife that is three times
than the stainless steel knives we use. The scientists are from the University of Maryland. Researcher Teng Li said wooden knives would add to the
of wooden utensils
found in kitchens across the world. He said: "In our kitchen, we have many wooden
that we use for a very long time, like a
board, chopsticks, or a
pin. These
knives can also be used many times if you resurface them and sharpen
."
