Kraft Tool Co.® CF163 6" x 3" Stainless Steel Cement Edger with Wooden Handle 6 per Case, 0.25" Radius. The 6" long stainless steel blade moves smoothly along edges of concrete sidewalks and slabs. This edger creates a 1/4" radius, with a 3/8" lip, on the edge of concrete slabs to prevents the edges from chipping with wear. The 3" wide tool provides the perfect amount of coverage on sidewalks and small projects. A steel mounting welded to blade attaches the smooth wood handle.
