Abstract
An apparatus for cutting material or grooving concrete has a housing including a curved top for partially accommodating one or more circular saw blades. The housing has a bottom having an opening permitting partial protrusion of the saw blade into cutting engagement with the material or concrete to be cut or grooved. For manual propulsion of the housing along such material or concrete, a curved handle is located on the housing top and has identically dimensioned first and second handle portions extending in parallel to the partially accommodated and protruding saw blade or blades in opposite directions from a central location on the housing top situated opposite the mentioned bottom. The partially accommodated and protruding saw blade is rotated and the housing including the mentioned bottom is maintained in spaced relationship to the material to be cut or concrete to be grooved during operation of the saw blade or blades.
