Would a tennis racket be a good weapon during the zombie Apocalypse?

I was think of what to do during the zombie Apocalypse and I realized I have no weapons! I'm broke and jobless and we aren't exactly "rich". The only things that I have that would kill a zombie would be my sisters metal tennis racket, a tenor saxophone, dull kitchen knife and a TV.
Update: Honestly, how many people can afford guns. I can't.
Update 2: Where would you get a kanta (that, and I know clue how to use it)
