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.
