The Model 24 Stielhandgranate was the standard hand grenade for the German Army from WW1 until the end of WW2. The distinctive appearance gave it its slang name of ‘potato masher’ or ‘stick grenade’.
the Stielhandgranate went through a number changes before a settled design emerged in 1917. The WW2 version had a smaller head and the belt clip was removed. All these changes were aimed at producing a lighter grenade that was cheaper and easier to manufacture. The Model 24 was replaced by the Model 43, but both remained in service until the end of the war.
