Discushandgranate

0:0:0 The M17 Discushandgranate (Discus hand grenade) was a German impact grenade designed during World War I. Inside the grenade, four striker pins were held safe by a pen. When thrown like a discus, the pins would release the pen due to centrifugal force, arming the device. On impact, the striker pins would return, setting off the grenade.
