Synthetic Soft Rubber Cutting Board for Professional Chefs. For professional or home chefs with high quality knives, ensuring a sharp blade is critical for efficient use in the kitchen. Rubber cutting boards are widely considered by knife experts and chefs to be the highest quality cutting surface, due to the softness of the material and extremely low wear on knives. Our boards are made from nitrile butadiene rubber, a synthesized compound that provides excellent wear and scratch resistance to ensure a super long life to the cutting board. This material is approved for food use and is widely used by chefs in Japanese restaurants to ensure a finely honed edge. Well sized at 18x12 inches and 0.5 inches thick, this medium sized board can be used for all standard kitchen tasks from prepping vegetables to cutting meats. The non-porous surface will not take on stains, odors or water, ensuring a near maintenance free performance. To clean, simply hand wash using hot water and soap. Unlike plastic cutting boards that develop deep grooves, a washing machine is not necessary to clean a rubber cutting board and there are no deep grooves that will develop due to the superior material surface. Includes round corner hole for hanging and drying.
