    Abstract: Post notch forming tool mounted on a handheld saw blade for forming a notch in a post end. The tool has a base, a handle, and two L-shaped members with bolt assemblies for attaching the tool to the saw blade. The base has a first extended lip which slides downwardly along the post's outer surface to guide the tool to form a 3-inch notch. A spacer member is selectively attached to the L-shaped members and has a second extended lip which slides downwardly along the post's outer surface to guide the tool to form a 1½ inch notch. Method steps include using the power saw blade to form a transverse cut intersecting the longitudinal axis, using the extended lip of the base to form a 3-inch notch, or attaching the spacer member and using its extended lip to form a 1½ inch notch in the post's outer surface.
