S84/98 III bayonet
The S84/98 III was the standard bayonet for the Karabiner 98k rifle. Origins 
The S84/98 III was the last production of the S84/98 German bayonets. It originates from the 1871/1884 bayonet the first ever standard issue rifle bayonet for any army which was adopted in the German Empire for use with  the 1871/1884 rifle. This was a modification of the Mauser Model 1871 the first Mauser rifle which fit it with a 8-round tubular magazine designed by Alfred von Kropatschek. This was the first repeating rifle of the German armed forces although it was quickly replaced by the Gewehr 1888 made in response to the Lebel Model 1886 rifle, the first rifle to use smokeless powder. The first pattern of S84/98 or M1884/98 bayonet was the 1871/1884 bayonet adapted so it could be used on the Gewehr 98. This was replaced in service by the 1898/05 bayonet. However during World War I the S84/98 began to be produced again under the designation S84/98 II. The German Imperial Army used this bayonet in World War I as a way of conserving scarce resources. The S84/98 III was production of the S84/98 bayonet  during the late Weimar period and during the time of Nazi Germany. Production
