These extra thick cutting boards will last a lifetime. They are 1.5 inches thick and measure 18″ by 12″. They are finished with food safe mineral oil and beeswax which can be re-applied as it wears off over time. These boards are available in a variety of maple (lighter wood) and walnut (darker wood) patterns. These boards are handmade from rough timbers in my workshop in Edmonton, Alberta, Canada with FSC certified hardwoods.
