Split will do far more than that.
It could easily have been used to create the cut you were after.
Parts can be split removing geometry or creating multiple solid bodies.
Split can also be used to split individual faces so that they can be colored individually or edited individually.

Attach your file here if you would like to see how split could have been used to edit your geometry.
