Answer 1

There is a pin inside that holds the striker in place, when you remove the pin, the striker presses against a part in the grenade that starts a small “fuse” that within about 5 seconds, ignited the materiel inside the grenade, causing explosion. The “shrapnel” (shell) of the grenade causes damage, as well as the explosion causes damage as well
