One of the standard-issue grenades for the German forces during WWII, the Stielhangranate 39 was often referred to as the stick grenade, or potato masher, due to the odd long-handled shape. A later version of the Stielhangranate, knonk as the 43, moved the ignitionfuse to the top of the grenade, enabling it to used as a mine as well as a grenade. There was also a version of the Stielhangranate known as the Nebelhangranate (Fog-grenade.) that was used as a smoke grenade.
