I ordered the oil-rubbed bronze and they are stunning.  They look very expensive.  Nice size, not too small and no rough edges .  They are a nice heavy weight and have a substantial feel.  The shape is slightly oblong, almost perfectly round but not quite, giving the knobs a hand forged feel without being too primitive.  I'm using in a kitchen makeover with ivory shaker cabinets that are distressed in chocolate glaze and they are perfect.  I can easily see them used in an industrial or Shabby Elegance style as well.  For those who want to mix the knobs with cabinet bin cup pulls, I found a braided accent cup pull, Cosmas brand, that coordinates beautifully.
