The present invention is a steering guide for surface cutting machines. The steering guide is made up of two sighting means that are connected to a surface cutting machine by a guide arm and are configured to align with the cutting edge portion of the saw blade. The first and second sighting means are visible by the sawyer while operating the device. Since the first and second sighting means are configured to align with the saw blade along a straight line, aligning the first and second sighting means with the guide line also aligns the cutting portion of the saw blade with the guideline. This enables the saw blade to be kept in alignment with the guideline while moving along a surface to be cut.
