I purchased these in both 3" and 5", as well as the colors "gunmetal" and "black bronze".  They have a nice, substantial feel.  The gunmetal is quite the unique color.  It has somewhat of a mirror finish, and can look anywhere from bronze to a dark brass, depending on the light.  It looks great with our medium oak cabinets.  The black bronze, on the other hand, is a very matte finish.  Almost a soft black.  I used that on our white cabinets.  Even with a variety of sizes and finishes (I even bought knobs to use on uppers), everything pairs together nicely.
