WW2 German K-98 Bayonet with Frog 
 
When issued the Karabiner 98k came accompanied with assorted accessory items including a sling, a protective muzzle cover, and for field maintenance a Reinigungsgerät 34 or RG34 kit. Introduced in 1934, the Reinigungsgerät 34 consisted of a flat 85 mm (3.3 in) wide by 135 mm (5.3 in) long sheet metal container with two hinged lids carried on the person, which held an oiler, a take down tool for removing the floorplate and cleaning the receiver of the rifle, an aluminum barrel pull-through chain, a cleaning and an oiling brush, and short lengths of tow used as cleaning patches. From 1905 until 1945 the German military used Ballistol intended for cleaning, lubricating, and protecting metallic, wooden and leather firearms parts.
 
The Karabiner 98k rifle was designed to be used with an S84/98 III bayonet. The S84/98 III had a blade length of 252 mm (9.9 in) and an overall length of 385 mm (15.2 in) and was accompanied by a bayonet frog. The Seitengewehr 42 or SG 42 was a shorter multi tool combat knife that could also be mounted as a bayonet on the Karabiner 98k rifle. The SG 42 was issued in small numbers.
