A push stick, push shoe, or push block is a safety device used when working with stationary routers, jointers, or power saws such as table saws or bandsaws. The purpose of a push stick is to help the user safely maneuver a workpiece, keeping it flat against a machine table or fence while it is being cut.
Types of push sticks
There are several different categories of push sticks, and many people adapt their own designs.
