I currently live in a home with an egg style knob that is hollow and not a very good quality. I ordered this ONE knob to see if I will want to used this style in the home I am building. The quality far exceeds the one that is in my home now. The size of the knob itself is smaller, which makes it more esthetically pleasing. I see the patina already starting on this unlacquered brass and I love it! It's hard to find a modern mortised knob with a skeleton key.
