Bill R expounded:

DO NOT use "rebar" for plant supports. The rust from them
can kill your plants and they look like crap after just a
few weeks. There are MUCH better items to use for plant
support.

No, rust won't kill your plants, and your tomatoes should be big
enough in a few weeks that you won't even see the rust! Many people
use rebar, I prefer the plastic coated metal rods (I pay for pretty).
