If you were home alone and people broke into your home and gave you no choice but to fight back, what weapons would use to quickly defend yourself?

I don't have a gun. So sadly I can't put my years of call of duty training to good use. šŸ˜‚ But I do have a hammer, a bat, some knives and pepper spray in my room that I could quickly grab.
