ABSTRACT:
A modular, grout removal tool of adjustable thickness, to better accommodate grout joints of varying widths on all types of tiled surfaces. The tool has a handle with a pear-shaped cross section and a protrusion extending from and continuous with its substantially rectangular base. The protrusion has a substantially rectangular cross section and a lower relative height than the rest of the handle, which affords the tool access to hard-to-reach grout joints, such as those situated under overhangs created by cabinet and appliance edges. The protrusion also functions as a thumb rest during use. Rectangular flanges at the bottom of the base curve inward to define a slot extending into the base for a plurality off carbide-tipped saw blades. The blades have apertures aligning with apertures in the flanges to receive securing screws upon insertions of the blades into the slot. The blades are available having different thicknesses, so that using one blade, or a combination of blades, affords the grout-cleaning tool of the present invention modular properties, ultimately making it better suited for use with grout joints having a variety of physical characteristics. The handle shape provides a comfortable fit in the hand of a user, allowing it to be firmly grasped for manual reciprocation in grout removal and restoration. Furthermore, the relatively large modular grout-cleaning tool affords greater leverage and control, making grout-related tasks more efficient and less tiring.
