How to delete in terminal from "/" to "/"?

Im using Kitty emulator and bash shell. I know that Ctrl+w I can delete **a word** in terminal (like Ctrl+Backspace). But what if I have something like this:

sh /home/user/dir1/dir2/file.sh

I just want to delete the file.sh? I can't delete with Ctrl+w because then the **whole line will be deleted** and I don't want to delete it manually. Any advice how to delete from only one path element?
