摘要： A saw tooth includes a body, a plurality of petals, and a plurality of inserts. The body has a forward surface defining a perimeter, a rearward surface, and, a plurality of sides extending between the forward and rearward surfaces. Each petal has a forward surface and a rearward surface, and the rearward surface defines a perimeter. The petal is coupled to the forward surface of the body. The perimeter of the rearward surface of the petal does not extend outwardly beyond the perimeter of the forward surface of the body. Each insert is positioned between two of the petals, is coupled to the body, and has an outer side. The outer side of the insert extends outwardly beyond a corresponding side of the body.
