Proper carving technique:
Ideal cutting conditions are achieved with the cutting edge bevel riding flat on the surface being cut; i.e., just as a chisel or gouge is used. The proportional relationship between the depth of cut and the forward tilt of the tubular blade enables you to steer the cutting path up or down by raising or lowering the handle. The tool is balanced on its bevel, and can generate any fully faired 3D contour by cutting a succession of criss-crossing perfectly faired 2D paths.
The circular cutting edge lets the handle be rotated about its longitudinal axis to present the edge to the workpiece at an angle to the direction of the cut. This skew cutting action greatly improves the tool’s ability to cut curly grain, knots, and end grain. When carving, always try to cut at 45° to the grain direction, and roll the handle slightly left or right to find the cleanest cutting action. If the edge digs in, change direction until you get a clean cut. If the shave is hard to pull, you are trying to cut too thick a chip. Concentrate on learning how to limit the chip thickness. If the shave produces a wavy surface, cut in a direction more nearly perpendicular to the visible grain lines, hold the tool more firmly, and increase the downward pressure on the bevel.
Constant downward force is required to keep the edge bevel firmly in contact with the surface of the work. Hold the tool firmly, NOT loosely. Slice and scoop. Do NOT scrape!
