Type 97 hand grenade

The Type 97 hand grenade was the main grenade used by Japanese forces during the Second World War. It was more or less just the earlier multi-purpose Type 91 grenade with the attachment socket for a propellant canister deleted from the base, preventing it from being used as a rifle grenade or light mortar projectile as the Type 91 could be, and with the 7-8 second fuze replaced with a 4-5 second fuze to prevent the grenade being thrown back. 
Many Type 91s were retrofitted with this fuze: they were further modified by having their base threading drilled out, and had blobs of welding flux added to the lip at the top of the base so they would not physically fit inside a mortar or rifle grenade launcher. For identification, the bases of these grenades were painted white: any grenade that appears to be a Type 97 but has a white base with a hollow in it is actually a modified Type 91. Without a white base but with a visible recessed socket, it is a regular Type 91. With a white base and no hollow, it is an error, as no grenades were marked in this way.
The grenade still suffered from the same bizarre fuze design as the Type 91, extreme variations in fuze burn time, and was still not particularly effective compared to other WW2 designs due to its small explosive content and cylindrical body which made throwing it uphill a hazardous activity.
