What percussion instrument is not part of a stranded drum set of drum kit?

A wood block is kind of a drum "accessory". The Essentials of a standard drum kit are the following: Hi hat,Ride and Crash cymbals and mounted tom toms, floor tom, bass drum and snare drum. Of course with that you also need the bass drum pedal,Hi hat stand, Cymbal stands, tom holders, and etc. A wood block would be added if needed but it is not essential to a standard kit.
