A machine blade for food production, comprising a cutting body and a fastening portion for fastening the cutting-machine blade to a rotary drive,

• wherein the cutting body has a central area defined by two lateral surfaces and edge regions adjacent thereto,
• wherein a thickness of the cutting body decreases in a respective edge region starting from the central area towards a respective edge of the cutting body,
• wherein the cutting body has at least one cutting bevel with a cutting edge at a front edge of the cutting body with respect to a direction of rotation intended in operation,
• wherein the machine blade is designed to be driven in operation in rotation about an axis of rotation and a radius of the machine blade extends from the axis of rotation to an outer edge of the machine blade, and
• wherein the cutting body, starting from the axis of rotation, is free of openings or apertures over ⅗ of the radius and in that the cutting body has one or more relief openings exclusively in the central area of the cutting body, all of which are arranged in an outer section of the central area which extends beyond ⅗ of the radius.
