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.[1] 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.
Push blocks typically are made from a thick block of wood with a handle and a hook on the back to hold onto the workpiece.File:Table saw push block.jpgA push block, used on a table saw
Push pads typically consist of one or two handles and a flat pad with a rubber underside to increase friction with the workpiece. They are typically used with jointers and router tables.
Microjig's GRR-Ripper is a hybrid push device that combines characteristics of a push block with a push pad. It uses an adjustable base which allows it to straddle a table saw blade or be used as a push pad.[2]
