The 6" long blue steel blade moves smoothly along edges of concrete sidewalks and slabs. This edger creates a 3/8" radius, with a lip, on the edge of concrete slabs to prevents the edges from chipping with wear. The 6" square tool provides the perfect amount of coverage on sidewalks and small projects. The tempered crucible spring steel provides the proper amount of "give" for the perfect feel when working on slabs. Three rivets secure the steel mounting to the blade. The rivets are ground for a smooth perfect finish. A comfortable wood handle completes the tool. Proudly made in the USA.
