Function: It allows for precise, straight cuts on various types of tiles without the need for electricity or water, unlike wet saws.
Components: Key parts visible include:
A long, flat base to support the tile.
Guide rails along which the cutting mechanism slides.
A scoring wheel (not clearly visible but implied by the mechanism) that etches a line on the tile's surface.
A handle and a breaking mechanism (the black part near the handle) used to apply pressure and snap the tile along the scored line.
