Good kitchen knives require a good surface. If the surface is harder than your knife, the knife will be damaged. Global's wooden cutting board is made of silver oak, which is a gentle material that is excellent for cutting boards. The cutting board has a number of smart functions: dimension scale for quick and even measurement, continuous bolts to adjust the board with, friction cloth so that it does not slip, and oil to treat the wood with. The board is available in three supported sizes.
