Fragmentation mine
From Tardis Wiki, the free Doctor Who reference
A fragmentation mine was a weapon used by the Sontarans. According to the Tenth Doctor, they were semi-sentient so often inflicted lethal wounds. In the 41st century, Fliss Keeley was injured by one. (AUDIO: The Trojan Dalek)
The Sontarans also used fragmentation grenades. One was kept in the Black Archive. (AUDIO: Traitors' Gate)
