A plunger element or key I 5 is slidably positioned in the bore of the metal casing I6 which is embedded in the end portion of the wooden handle 3 and which. has threaded in its inner end a ‘cap IBa which provides an annular shoulder or abutment I 6b adjacent the inner endv of the casing.

described, the detonator may easily be removed as a pivot, the said head portion constituting the maiorweight of the grenade. This spinning motion gives rise to considerable centrifugal force exerted at the handle end of the grenade. The
