    Abstract: A saw guide is attached to a circular saw to help make straight, accurate cuts along a line a desired distance from an edge of an object, such as a piece of wood. The guide includes a fence that can fold up by one or more hinges to store the fence out of the way when not in use, allowing the saw to be used like a conventional saw. The fence can be pivoted down, extending at about a 90 degree angle from the saw base, generally parallel to the radius of the saw blade. The distance from the saw blade and the fence can be adjusted and locked into place to make a cut having a desired width.
