what can I do to change antique brass cabinet knobs to look like the newest styles of the black/brown rodiron?

I have a large amount of cabinets in my kitchen and would like to change my handles without having to buy all new knobs. I would like to do something to change the look to a more now style black/brown rod-iron wthout ruining the knobs (which were fairly expensive and were just purchased about 2yrs ago. I am adding the black asian woods throughout my kitchen/dining area and would like to change these to go with my black granite and corian countertops...need to modernize the 17 yr old oak cabinets with some new bling!

1. They have many decorative finishes in spray paints that you can use (patina, rust, etc). I did a decorative finish with the brass knobs in my kitchen and I like the look of it! I found it at Menards and think the brand was a Rust-oleum.
2. get sandpaper an sand the knobs first, then get a metal primer an spray each one, then paint your knobs that's it have fun
