Does this construction even make sense? By definition it is a surface of constant energy in k-space, so for the free electron it is a sphere. But for metals you have band structure so that a given k-vector can have several different energies associated with it.
Which of these are to be chosen?

For free electrons (or for an approximation), choose the model for free electrons, otherwise don't choose that?
Electrons in metals see a potential structure, if this can be neglected or not depends on your problem.
