Toolmaker’s clamps are fairly simple in their operation and how they work.

The centre screw and outer screw need to be turned anti-clockwise to open the jaws. The centre screw and outer screw must be turned anti-clockwise to open the jaws.
The two screws must be turned anti-clockwise until the jaws open wide enough to fit your workpiece. When the jaws are open wide enough, you can insert your workpiece.
The jaws of the clamp are parallel meaning your work piece will fit comfortably between the upper and lower jaw, depending on how flat your work piece is. The jaws of the clamp are parallel, so if the opposing surfaces of your workpiece are flat, they should hold it securely in place.
The jaws are then placed around your work piece. The screws need to be turned clockwise until they are finger tight. Once your workpiece is in place, the screws must be turned clockwise until they are finger tight.
Finally, once the screws are finger tight, a tommy bar is used to tighten the centre screw as tight as possible to secure the work piece in place. The holes in each screw head allow a tommy bar to fit. A tommy bar can then be inserted into the hole of the screw head and used to gain extra leverage when tightening.
