Original German WW2 Solid Wood Stick Training Grenade M24

Stielhandgranate is the German term for "stick hand grenade" and generally refers to a prominent series of World War I and World War II–era German stick grenade designs, distinguished by their long wooden handles, pull cord arming and cylindrical warheads. The first models were introduced by the Imperial German Army during World War I and the final design was introduced during World War II by the German Wehrmacht.

The distinctive appearance of the Stielhandgranate family has led to them being called "potato mashers" in British Army slang, and they remain one of the most easily recognized infantry weapons of the 20th century.

Model 1924 (M24)
Upon the German Empire's defeat at the conclusion of World War I, the collapse of industrial capability and military strength of Germany left many projects and ideas forgotten for years. When the newly created Weimar Republic progressively began to repair both the physical and economic devastation, a slow rebuilding of the armed forces was allowed under the limitations set by the allies.

The Weimar Republic revived the Stielhandgranate, and created a new version in 1924, the "Model 1924 Stielhandgranate" (M24). While retaining the same explosive and fuse, the main distinction between the M24 and the original M15 is a slightly shorter charge head and the removal of a belt carry clip. Another change in the design was a lengthening of the wooden handle. The intent of these design alterations was simply for mobility; German soldiers could easily (and often did) tuck the grenade in behind their uniform's belt, held tight and secure. Being slightly lighter, and smaller in thickness, this improved overall use.

The M24 is well known as the standard hand grenade of the armed forces of the Wehrmacht during World War II. Adapting to the rapidly changing field of modern warfare, German soldiers would carry the M24 directly in front, allowing quick and easy access. However, in the later years of the war it was often advised to carry them in a different manner, as it was very likely any sort of explosion or heat could light the fuse from the grenade on the belt, resulting in unnecessary casualties.

The Model 24 Stielhandgranate was stored in specially designed crates during transport, which could carry up to 15 individual grenades. As a safety precaution, units of the Wehrmacht were advised to only insert the actual fuse assemblies when about to go into combat. Later in the war, however, many soldiers of the Wehrmacht would always have their weapons ready, due to the fierceness seen in the Soviet Red Army in the east and the progressive advance of the Allies on the Western Front. During production, a reminder was stenciled on each explosive charge: Vor Gebrauch Sprengkapsel einsetzen ("Before use insert detonator").

The Model 1924 was rather ineffective by itself at damaging or disabling an enemy armored vehicle or destroying fortifications. It also lacked the shrapnel effect of most other grenades of the time. To overcome these faults, various German industries during World War II produced a number of variants that widened the utility and capability of the M24.
