Japanese grenade fuzes for a stick grenade?

[daleville]

These had a tag that said they are for a Japanese stick grenade, the wire runs up the inside of the fabric string. Are they for a type 98 stick grenade?

I found a description of the fuze activation; it mentions a sanded string that when pulled ignites the fuze:

...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 exposed 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 igniting 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 grenade

Appears we could be right, the dark colored piece is sand paper like material.
