A masonry trowel is a hand tool used primarily in construction for shaping and applying mortar or concrete. It typically features a flat, pointed blade attached to a handle, allowing for precise control when working with materials like bricks and stones. The design helps masons create smooth surfaces and fill joints effectively. Masonry trowels come in various sizes and shapes, including pointed trowels for detailed work and margin trowels for tight spaces. They are essential for professionals in the construction industry, ensuring that structures are built with strength and durability.
