It might be easy to glance over the Madebywho Chop Board and see just a plain wooden panel; however, the designer did actually bestow it with a subtle surface feature. The elongated rectangles are not symmetrical from end to end: one side has been carved out to take a subtly lower grade.
This very delicate division between the high and the depressed halves serves to help the cook separate parts of a meal. During the food preparation process, diced items might be pushed into the lower area so that this bordered section of the cutting board can help to guide ingredients into a pan. Alternatively, the Madebywho Chop Board would work great as a serving tray, presenting different edibles in different areas.
