A laser beam deflector is useable for protecting underlying portions of an item during laser cutting of overlaying stock. The deflector has a base surface width greater than the overlying stock to be cut and a smooth deflecting surface of an arcuate cross-sectional configuration. The deflector is positionable between the overlaying stock and the underlying portions desired to be protected with the deflecting surface immediately adjacent the overlaying stock.
