Method for removing trip hazards in concrete sidewalks

A method for cutting a chamfer along an upper abutting edge of a first of two abutting concrete slabs, said abutting edge being elevated above an upper surface of said second concrete slab, the method comprising the steps of:

• providing a generally circular, rotatable concrete saw blade that is coupled to a right-angle grinder motor with a blade-mounting hub having no blade attachment hardware projecting below a lower major surface of the blade;
• making a planar cut at a desired angle beginning a distance from said upper abutting edge, said desired angle being selected so that a projection of a bottom surface of the planar cut intersects an upper abutting edge of the second concrete slab, the planar cut creating a cantilevered ledge above the planar cut;
• fracturing and removing at least a portion of the cantilevered ledge from the slab whenever an edge of the cantilevered ledge is proximate the hub;
• and
• continuing the planar cut until the cantilevered ledge is severed from the slab.
