  • Patent number: 4699063
    Abstract: In an explosive practice hand grenade a ring containing inorganic particles is encased in a shell and substantially completely enclosed by an explosive charge. The ring is practically pulverized during detonation so that no effective fragments are formed. The ring is manufactured by compressing a metal or metal oxide powder. The inventive explosive practice hand grenade has substantially the same properties or characteristics as a combat-duty fragmentation hand grenade, however, has the advantage that the inventive explosive practice hand grenade, during its explosion, generates only a minimum fragment action and thus ensures the safety of personnel to be trained.
