Pulling the pin strikes a fuse. Putting it back doesn’t help.

Pulling the pin doesn't strike the fuse. The pin is the final safety locking a lever called the spoon down. As long as that lever is held down, the pin can be reinserted. The lever is under spring tension, and when it flies up, it strikes a primer that ignites the fuse.

Wrong. The pin holds the lever in place, as a safety. You pull the pin, and then when you let go of it, the lever itself has a mechanism that scrapes the fuse. Other designs have different mechanisms to time them, but not that one.
