Setup
The background is red presentation board. A small continuous-light lamp behind the wrench lights the top of it and creates the direct reflection on the top left area. A white reflector redirects light from the lamp onto the wrench. The lamp is also fitted with matte black aluminum foil to limit the light falling on the background, which produces dark tones. A small flashlight (torch) brightens the background behind the jaws. A flashlight behind the subject creates the direct reflection on the bottom left curve and lights the right hand jaw. Another flashlight brightens the adjusting knob and the surrounding area. A polarizer eliminates glare on the highest, narrow strip of red paint. The image was captured in a vertical orientation purely for the ease of constructing the setup and was rotated 90 degrees counterclockwise.
EDIT: I added the monochrome version, which is explained later in the thread.
