Abstract

A blade (12) for a digging assembly comprises a base portion (24) and a terminal portion (26) remote from the base portion (24). The base portion (24) is wider than the terminal portion (26), and the blade tapers in width between the base and terminal portions (24, 26). First, second and third sharpened edges (28, 30, 32) are provided on the blade (12), each having flanks (34) that subtend an angle of at least 90°. Each of the flanks (34) are skewed in relation to the respective flanks (34) of the other edges. The orientation of the flanks (34) of the sharpened edges (28, 30, 32) enables the blade (12) to exhibit a lifting effect when it is rotated through material on an axis in a digging assembly.
