I wouldn't even use a plastic board. The grooves made by blades are deep and bacteria grow inside them and very hard to clean. Cutting on glass is just ignorance. Yet I see a lot of people on here cutting their steak dinner on a glass plate and a pocket knife. Bamboo or wood, end grains are not hard to clean, dont be lazy and get a proper cutting board. Stop buying cheap plastic boards, almost no chef recommends a plastic board.
