A fragmentation grenade is a thrownweapon that appears in all of the Fallout games. Fragmentation grenades, or frag grenades, are small hand-thrown bombs. They contain a dense core of high explosives encased in a metallic body designed to fragment upon detonation. Wounding effects come from both the explosive blast and the propelled fragments. The metallic case of fragmentation grenades may be preformed into a matrix designed to break apart evenly. Fragmentation grenades may either be spherical shaped or attached to a throwing handle (stick grenade) and armed with contact or timed fuses.
