Photorealistic studio product still life: an old hacksaw placed horizontally against a seamless pure white background. The rectangular metal frame is rusted reddish brown; the left side has a worn black handle; the bottom blade is blue-gray with reddish rust patches; the right end has a wing-nut tensioner; the top crossbar has several round holes and a hook-like notch.
