Abstract: A cutting board provides support to large pieces of wood during cutting or shaping. The cutting board supports a piece of wood across its surface area to prevent the wood from bending, cracking, or breaking as it is cut. This allows the wood to be cut accurately and safely by a single person. The cutting board may include a generally planar work surface and have one or more openings. The one or more openings may be configured to reduce weight, allow clamps to be easily installed, and allow sawdust to escape. The cutting board may be placed on a variety of supporting structures or surfaces. In one or more embodiments, the cutting board may be modular to allow a plurality of cutting boards to be connected together to form a larger work surface. Other materials may be cut or shaped on the cutting board as well.
