A safety fuze for a hand grenade comprises a fuze body, a delay case assembly, an initiator lever assembly, and a cover assembly. The fuze body has a head, a stem, and a central portion, and a bore extending longitudinally therethrough. The delay case assembly is matingly received in the bore and includes an upper primer portion containing a primer in a primer holder, and a lower delay portion. A flat, circular seal is interposed between the base of the primer and the primer holder. A first annular seal is matingly received in a first annular channel defined between the primer holder and the delay case. A second annular seal is matingly received in a second annular channel defined between the delay case assembly and the bore. An annular gasket is matingly received in a third annular channel formed in the bottom wall of the central portion of the fuze body. The initiator lever assembly comprises an elongated initator lever rotatably mounted to the fuze body head and a cover assembly removably mounted to the fuze body head using a hinge and hinge slot assembly. A rotatable safety latch is mounted on the cover assembly to maintain the initiator lever in its unprimed position. A projection on the initiator lever engages the safety latch to prevent its rotation. For a practice grenade, the bottom of the fuze body is open, with the delay case assembly extending therethrough and frictionally engaged by an annular gasket matingly received in a fourth annular channel formed in the inner surface of the stem.
