Nail bomb

The nail bomb is an anti-personnel explosive device packed with nails to increase its wounding ability. The nails act as shrapnel, leading almost certainly to greater loss of life and injury in inhabited areas than the explosives alone would. The nail bomb is also a type of flechette weapon. Such weapons use bits of shrapnel (steel balls, nail heads, broken razors, darts and bits of metal) to produce a large radius of destruction.
