ABSTRACT:
A hand held woodturning tool for cutting a turning timber workpiece. The tool has a long straight rod-like, tool shank and, a cutting head at one end of the tool shank and rigid with the tool shank. A hole is formed within the cutting head and has an end opening. The end opening has a periphery which is of continuous extent about the opening and which convexly arcs along part of the periphery, and an arcuate sharp cutting edge extends in a flat plane along a substantial section of the arcuate periphery part. An outer surface of the cutting head adjacent the periphery extends perpendicular to the plane containing the cutting edge and an inner surface converges toward the outer surface to form the sharp cutting edge. The tool is hand held and presented to a turning timber workpiece so that the outer surface of the cutting head adjacent the periphery rubs on a surface of the workpiece and the cutting edge engages the workpiece surface in a cutting action.
