We do housework and don't know much about what we do, so we poured the cement foundation (too stretched) and we need to cut a 10 foot line about 1 inch long. We used a heavy duty 4-1/2" DEWALT DW4725 full edge dry cut diamond saw blade and a 7/8" masonry arbor on an angle grinder to cut the line as deep as the blade would allow and then used that Stanley. FatMax chisel for beating off the ground where the angle grinder missed. It turned out great!
