Which tool is specifically designed with a face shaped like a chisel for trimming brick or stone?

The correct choice is the mason's hammer, which is specifically designed for working with brick, stone, and other masonry materials. The face of the mason's hammer has a chisel-like shape that allows it to effectively trim, shape, and break masonry materials. This tool is particularly useful for making precise cuts or adjustments to blocks or bricks during construction or repair work.

Mason's hammers typically have a striking side that can be used to drive the tool through materials, as well as the chisel side that assists in carving or trimming edges with accuracy. This dual functionality makes it an essential tool in masonry work, where precision is often critical to the overall integrity and appearance of the structure being built or repaired.
