Bowl basics: The three cuts to know
A bevel-rubbing cut [Photos A–C] yields the cleanest surface with the least amount of torn grain, so use it whenever possible. With this cut, the bevel of the tool contacts the workpiece while the wing removes the waste. The support provided by the bevel prevents tear-out and offers the best control of the gouge.
By contrast, during a shear scraping cut [Photo D], only the wing makes contact. Because of the severe cutting angle, use this technique for light cuts on the exterior only.
A scraping cut [Photo E] uses just the cutting edge of the tool and transfers the tool's shape to the wood, as when creating a square shoulder on a recess.
