What Is the Difference Between Satin and Brushed Nickel?

Satin nickel isn't technically a metal itself, but a nickel plating that is applied to pulls, handles and knobs through electrolysis and then treated with lacquer to dull the surface a little bit.

Brushed nickel receives its unique look when a wire brush is used to create abrasions on the surface, which is meant to get rid of its natural, more polished look.
