Circular edging tool for concrete

A concrete edging tool for forming a slot around a circular outer edge of a manhole frame or other circular objects, comprising:

• a tool body having a generally flat rigid bottom surface defining a plane, said bottom surface for engaging a generally flat top surface of a body of soft concrete partially encasing a manhole frame having a top surface and a cylindrical border formed around a center, and in which the flat top surface of the body of soft cement is generally co-planar with the top surface of the manhole frame;
• the tool body having an elongated rigid lip extending downwardly from said bottom surface;
• said lip and tool body being formed with substantially the same thickness over their extent;
• the lip having an outer concave surface that generally corresponds with the cylindrical border of the manhole frame;
• the concave outer surface of the lip being formed about an axis that is normal to the plane of the flat bottom surface and which passes through a center axis of the cylindrical border;
• and
• an elongated handle attached to the tool body and disposed with a longitudinal axis at an angle that is generally transverse to a radial line extending from a center of the outer surface of the lip, said handle extending substantially parallel to said plane.
