| Type 98 - Stick Grenade |
| Over-all length: 7 3/4 inches. |

| Color: Body, black; handle, unpainted. |
| Total weight: 1 lb. 3 ounces. |
| Filling: Cast picric acid. |
| Weight of filling: 3 ounces. |
| Delay 4-5 seconds. |
|
Description: The body is cylindrical in shape and is made of cast steel 1/4- inch thick. The handle is turned from soft wood and slips into the steel body where is it held by three screws. This joint is sealed with a coating of tar. The screw cap at the pull end of the handle is of light, tin-plated steel. |
|
The fuze consists of a friction ignition composition with a sanded string running through it. This string extends up the hollow handle and is connected to a pull ring which is expo-sed by removing the screw cap at the top of the handle. |
|
Operation: The screw cap is removed from the top of the handle. The ring inside the handle is then pulled. This draws the sanded string through the ignition composition ignit-ing the 4 or 5 second delay. The delay train detonates a cap which detonates the main charge. |
|
This grenade has more fragmentation effect than the German high explosive stick grena-de. |
