Thank you for your question. Both the knobs and pulls seen in the kitchen above are made by Schaub & Company. They are both from the empire designs collection and are shown in a polished nickel finish. Here is a link from the Schaub & Company webpage where you can see there are other finishes available. The knobs are on page 2.

Since there is no price listed, I also included links for both from JustKnobs.com, which have pricing and a little clearer picture of the details (like the curves on the knob and the feet on the pulls).
