A saw blade includes a saw blade body having a first face, a second face opposing the first face, and an axis of rotation extending between the first face and the second face. The saw blade includes a cutting element disposed about an outer periphery of the saw blade body. The saw blade includes a spline arbor interface portion disposed about an inner periphery of the saw blade body and having a peripheral face defining an eye disposed substantially collinearly with the axis of rotation of the saw blade body. The saw blade body defines a relief portion extending along at least a portion of an edge between the peripheral face of the spline arbor interface portion and at least one of the first face and the second face.
