Abstract
A detonator includes a pyrotechnic material and a first explosive. The pyrotechnic material ignites in response to a percussive impact, and the explosive detonates in response to the ignition of the pyrotechnic material. The detonator may include a plate, and the plate forms a projectile in response to energy released by the ignition of the pyrotechnic material to detonate an additional explosive. A passageway of the detonator may be located between these explosives, and the passageway may include a cross-sectional profile that substantially varies along a path between the explosives.
