What tool is used to shape or alter the edges of a stone tile?

The appropriate tool for shaping or altering the edges of a stone tile is the round shaping stone. This tool allows for more controlled and precise adjustments to the tile's edges, enabling the craftsman to create the desired shape or finish. The round shaping stone can effectively smooth out rough edges and refine the contours of the tile, which is particularly important for achieving a professional and polished look in stone tile installations.

While other tools are useful in the tile installation process, each serves a different purpose. A chisel is typically used for breaking or cutting hard materials, which may not provide the fine detailing required for edge shaping. A straight edge is mainly employed for measuring and guiding cuts rather than altering the tile's shape. A tile cutter is designed for cutting tiles to size but does not offer the same versatility as a round shaping stone when it comes to refining edges and creating custom shapes.
