  • Patent number: 6044740
    Abstract: A push stick for use with stationary power tools including table saws and shapers. The push stick has a flat base plate that can ride on the surface of the power tool thereby providing stable operation with a resulting increase in safety for the operator and more accurate cutting. A handle of the push stick is placed at an optimum angle to provide both downward and forward pressure on a work piece. The push stick may also be equipped with a variable handle angle to optimize its use with different power tools. The base plate of the push stick may be adjustable in thickness to accommodate work pieces of different thicknesses.
