Demolition tools, a double saw and a leveling sight
Steel-tipped maces and wedges for razing walls, tools for clearing underwater stones
This sheet collects instruments for demolition and construction work. A double saw is described that cuts equally when pulled and when pushed, beside a double bellows; heavy steel-headed maces drive chisel-footed wedges into masonry to begin the ruin of a wall, and a wooden mallet strikes a wedge. Five hooked tools are shown for lifting stones, coarse sand and gravel from under water, and at the foot an eye sighting through two aiming marks serves for leveling.

Double saw cutting on push and pull
A double saw drawn along the top of the sheet works as much in pulling as in pushing, so it cuts on both strokes. It is stretched between two handled end-frames.
Steel-headed maces and wedges to demolish a wall
Heavy maces (marked 30 pounds, 3 braccia and one braccio) drive wedges into masonry to begin its ruin. Each wedge is a braccio long and an eighth thick, its head of tempered steel and its foot shaped like a chisel — a method for taking a wall down.
Wooden mace striking a wedge
A mallet that beats a wedge is noted as being made of wood. It works together with the steel wedges shown above.
Five tools for clearing stones under water
A row of five hooked and forked instruments is provided for removing stones that lie under water, such as coarse sand and gravel. They would serve for clearing a river or foundation bed.
Leveling sight through two marks
At the foot, an eye sights across two aiming marks toward a mound, an arrangement for leveling. The single-word caption names its purpose.
