This is probably (not guaranteed) my last photo of the pipe wrench.
Setup
The background is red presentation board. A small continuous-light lamp on the front left lights the front of the subject and its lower teeth. That lamp is fitted with matte black aluminum foil to limit the light falling on the background. Two flashlights, one directly behind the subject and one behind and slightly to the right of the subject, create the direct reflections that outline the upper teeth and throat. A black flag positioned between the subject and the lens eliminates flare in the bottom of the image created by the flashlight placed directly behind the subject.
