"Weslock has a little niche in the market with Black Door Knobs, and their bordeau levers that are also available in a black finish. These have been quite popular lately I have noticed. Not sure exactly why, I think they look great. It's interesting to see how sales go. Some days we'll sell a great deal of Oil rubbed Bronze, the next it all satin nickel. Makes me wonder sometimes if people get together and time their purchases. The Impresa knob is a squashed round shape meaning it is round from the front, squashed to an oval shape front to back. The locking mechanism on the privacy knobs is on the rosette rather than the knob itself, and releases upon turning the knob. Its a great knob for the price in my opinion. And it is available in 8 finishes like the Bordeau lever."
