Type 67 hand grenade

During the Second Sino-Japanese War (1937–1945), the Chinese designed and produced a grenade based on the Model 1924 which was used by the National Revolutionary Army. Such grenades were the main type of grenade used by Chinese forces during the whole war. In 1939, a new design with a smaller handle and much more compressed explosive load began trials. The resulting model was lighter and more powerful and the ordnance office decreed it to be the new standard type in all arsenals. Known early copies of the Stielhandgranate include the Type 51 hand grenade (Chinese: 51式木柄手榴彈, lit. 'Type 51 Wooden Handle Hand Grenade'). After World War II, the People's Liberation Army standardized a variant of the grenade, designated "Type 67". The Type 67 became the standard hand grenade for the People’s Liberation Army, which becomes the basis for the Type 77. The grenade was first used by Chinese troops in the Korean War.
