Hawk (plasterer's tool)
A hawk or hod is a tool used to temporarily hold a portion of a viscous material, so that the user can repeatedly, quickly and easily get some of that material on the tool which then applies it to a surface. A hawk consists of a board about 25 cm (9 inches) square with a perpendicular handle fixed centrally on the reverse. The user holds the hawk horizontally with the non-dominant hand and applies the material on the hawk with a tool held in the dominant hand.
Hawks are most often used by plasterers along with a finishing trowel to apply a smooth finish of plaster to a wall. Brick pointers use a hawk to hold mortar while they work. Hawks are also used to hold joint compound for skim coating.
