Abstract

A rotating tool such as a saw blade has a substantially planar body with a mounting arrangement at the centre of the planar body. A plurality of cutting elements are distributed around the periphery of the body. At least one energy absorbing crack penetrates the body. The energy absorbing crack has opposed crack faces with the faces touching along substantially the entire length of the crack. Each crack ends, at each end, at a crack arresting feature. The cracks may be formed by a full or partial shearing action followed by forcing back into alignment.
