Each color is specific to a different type of food, preventing cross-contamination during meal prep. At the same time, the surface doesn’t allow for grooving when cuts are made, which prevents bacteria from hiding out in those small spaces. Each of the boards features both centimeter and inch measurements along the edge to help create consistent sizes. Despite the tough surface of the San Jamar - CBG1824KC - Saf-T-Grip 18 inch x 24 inch Cutting Board Set, knives won’t dull as you make your cuts.
