ABSTRACT:
A cutting member and machine for cutting elongate members is disclosed. The cutting member comprises a body having a cutting edge defining a cavity such that the cutting edge contacts a surface to be cut at at least two points. The cutting machine comprises the cutting member, a weight pivotally connected to the cutting member to define a arm-weight assembly, and a driven member defining a central opening, wherein the arm-weight assembly is pivotally attached to the driven member so as to drive the cutting member in a circular path around the central opening, the cutting edge of the cutting member being biased inwardly towards the central opening by the weight and the resultant centrifugal force. The cutting edge of the cutting member may comprise a first cutting surface having a razor like leading edge and a second cutting surface which is positioned parallel to and adjacent at least part of the first cutting surface, the second cutting surface defining a surface to remove large amounts of material, such as serrated saw teeth or an abrasive medium.
