Fun fact: Before the deployment of Type 10 grenade in 1921,Japan only had impact grenade for their troops. Even though they made several variants of it, they didn’t give their grenade an official name, they just called it ‘‘urn-shaped grenade’’ or ‘‘grenade’’.
These types of grenades only explode while the firing pin on the top hit the target. They all have tail made with rope or fabric trailing behind the grenade ensures it travels headfirst.
Just for convenience, l am just gonna call them Type ___ grenade in this topic. Here’s the main two variants that I think it’s interesting to be add in game, the Type 40 and the Type 7 grenade.
Type 40 grenade(1907)
It’s the standardized version of the Type 38 grenade, which was designed during the Russo-Japanese War. The prototype version of Type 38 doesn’t have safety, so you need to insert the firing pin before throwing it.
The Type 40 also appears in the manga ‘‘Golden Kamuy’’
Type 7 grenade(1918)
Compare to Type 40, Type 7 grenade’s tail is made of rope. Only half of it is covered with fabric in order to hold the wooden base piece in place.
Type 7 without wooden base
Even though we don’t have the pictures of the cap of these grenade, according to the document I found. The cap is made of brass(黃銅)and the firing pin is welded together.
