US Patent 7861428 Push stick with slide-out ruler

A push stick comprises a body providing a bottom surface and a heel member that protrudes beyond the bottom surface; and a slide-out ruler that is selectably positionable to extend from the body. The push stick is a safety device that can be used to push a workpiece past a blade or bit while keeping an operator's hands out of harm's way. The ruler allows an operator to use the push stick to make measurements, such as setting the height of a cutting tool relative to a workpiece table.
