This is a simple picture to learn drawing a spanner tool. Spanner is a mechanical tool used to screw and unscrew nuts and bolts. Draw a tie shaped diagram. From either ends draw a curve projecting downwards, looking like the horn of a cow, which forms the head of the spanner. From the bottom of this horn, draw a handle. Within the handle, draw a rectangle and a small circle and shade the drawing and your spanner tool is complete.
