Kugelhandgranate

The Kugelhandgranate is the name given to a model of a hand thrown, fragmentation grenade manufactured in Germany also known as '''Mod. 1913'''.

Description
The body of the grenade is cast iron 8 mm thick, spherical shaped and externally segmented designed to produce between 70 and 80 fragments, a bronze-like stick (which is the igniter) is introduced to the spherical body. The filling was a mixture of black powder, barium nitrate, and potassium perchlorate, and does not require a detonator. The friction igniter consist of a bronze body with a central chamber filled with black powder and supplied with a 5 or 7 second delay, the powder train was topped with a priming wire made of brass with a loop at one end and serrated on the other. The serrated portion was coated with a mixture of ground glass, manganese dioxide, and potassium chlorate.

Method of use
To be used, the friction wire must be pulled from the igniter, starting the delay train at the last possible moment. To be done, a piece of leather was attached to the igniter with a snap hook, pulling this will remove the wire so the grenade can be thrown. A man with average strength could throw this grenade about 15 m.
