All I have are candles, water, salt, and feathers to represent the elements, as well as some fruit as an offering of thanks.
Those are the tools for your ritual. There's nothing that says you must have a sword or a wand or a chalice, unless you're a stringent follower of a specific tradition. We each practice as we feel most comfortable.
I really like the feathers idea -- I always used incense for air, but it often struck me as a little too fiery. I think I need to make some changes for my upcoming rituals.
