The Model 24 Stielhandgranate was the standard hand grenade of the German Army from the end of World War I until the end of World War II. The very distinctive appearance led to its being called a "stick grenade", or a "potato masher".
The Stielhandgranate saw his debut in 1915, when the first models of the Stielhandgranate 1915 saw service during the First World War. Those are the versions with a safety pin and not with a cord. To be easier in production, the Stielhandgranate was redesigned with a cord. It was followed by the Stielhandgranate 1916 but it was the Stielhandgranate 1917 wich will the perfect design. This was the same model like the 1915 with the 1916 cover cap. It was followed in 1924 by the most famous model of the Stielhandgranate family, the Sielhandgranate 1924. This type of grenade, featuring a high explosive charge (170 gram TNT) encased in a thin sheet steel can and with a B.Z.24 fuse. This was an example of an "offensive" (relying on blast effect), rather than "defensive" (fragmentation) grenade. A serrated fragmentation sleeve ("Splitterring") was adopted in 1942 which could be slid over the head of the grenade. Fragments of the sleeve would be scattered on detonation, making the grenade more effective against personnel.
The stick provided a lever, significantly improving the throwing distance. The Model 24 could be thrown approximately 27 m to 37 m. The stick design also minimized the risk of the grenade rolling downhill back towards the thrower when used in hilly terrain or in urban areas. It was followed by the Stielhandgranate 39, with 198 gram TNT. The design was also successful used by many other country's for their grenades. The Germans also had a smoke handgrenade, named the Nebelhandgranate 39. Also an anti-tank grenade variant saw some service, wich the idea dates from the First World War. The Gebalte Ladung.
