This is a drawing of a stylized object resembling a T-square with a spiral on one end. The drawing features a central object that resembles a T-shaped rod with a smooth, dark finish. The horizontal bar of the "T" is depicted as a delicate curve with one end curling into a tight spiral. The central vertical rod is straight and gradually tapers to a blunt point. Surrounding this main drawing are two additional sketches in light pencil. One in the top left corner hints at a cross-sectional view, while another on the bottom right corner shows a simplistic, elongated object resembling a dagger from a linear perspective. The entire composition implies a study or design process of artistic or functional tools.
