How do manufacturers make flat articles, such as cutting boards, out of bamboo – arguably one of the most round things in existence?

Answer 1

Using this cutting board as an example:

It’s not a single sheet of bamboo. It’s a bunch of strips of bamboo glued together to form a flat board, which is then sanded/ground down to round the edges and to form the channels around the edges. You can see in the images that the pattern of the knots is not consistent, which indicates that it’s not a single piece.
