nail bomb

Such weapons use bits of shrapnel (steel balls, nail heads, screws, needles, broken razors, darts and other small metal objects) to create a larger radius of destruction. Nail bombs are often used by terrorists, including suicide bombers, since they cause larger numbers of casualties when detonated in crowded places. Nail bombs can be detected by electromagnetic sensors and standard metal detectors.
