The blade has a material supporting surface (60) defined by the outside perimeter and the apertures, and is from between 80 % to 50 % of the area of the blade. When the blade of the material moving tool is inserted in material, it has an effective area (46) described by the perimeter of the blade immersed in the material, and a plurality of ringshaped apertures through the effective area of the blade. The blade has an effective material supporting surface (57) defined by the perimeter of the blade immersed in the material and the effective apertures, and is from between 80 % to 50 % of the effective area of the blade.
