Abstract

A simple modification to a standard increment borer handle is described that enhances use of the borer in situations where obstructions to the rotation of a normal handle prevents utilization of the full length of the borer. The modification, informally called the “Quad-B” (Brown's bent boomerang borer handle), involves bending both sides of the handle to ∼35–40°angles. Some potential uses of the modified handle are described.
