Karbidowka partisan grenade

A simple 3d model and renders based upon a type of improvised hand grenade made by the Polish resistance/partisans during the second world war to fight against the Nazi invasion of Poland when resources were lacking for the production of more professional munitions.

These sorts of grenades were made by re-purposing carbide lamps, a type of lamp that used calcium carbide hence the name together with water to produce acetylene gas which could be ignited to produce a flame for light. These carbide lamps would have been modified slightly to function better as grenades by removing most of the parts of the lamp but its fuel canister which were then filled with forms of explosives such as cheddite or ammonal, To make these now explosive-filled lamps into proper grenades all that was needed to do was outfit them with a proper fuze, in this case, a shortened Polish WZ GR 31 grenade fuze.

The Carbide grenades or Karbidowkas as they were known were famed for their great concussive blasts and the amount of shrapnel they produced since the things were rather huge for hand-thrown grenades which in turn made them rather heavy and unwieldy.
