M1 lighter friction fuse

[MINENAZ16]

I know the paper version called M1 (https://www.bulletpicker.com/fuse-lighter_-friction_-m1.html)
What is the designation of the metal version ? (https://www.105th.org/basic_gear/engineer/pull_fuses.html)



Now when I see this picture, I'm not sure these are metal.

I think these on the picture are also made of paper/cardboard.
