Push block for a woodworking apparatus

摘要

A push block for a woodworking tool comprises at least heel member at an end of the push block and the heel member is passively actuatable to an extended position to engage a trailing end surface of a work piece to advance the work piece by a working element. The push block also includes a wall member along a first side of the push block to serve as a barrier between a cutting element and an operator's hand. In addition, the push block includes a handle that is disposed obliquely relative to first and second sides and a longitudinal axis of the push block.
