Search on 'Metal Spinning' this is how sheet material can be formed into shapes like you want.

Ah, you mean half an egg longways not half an egg crossway which would be rotationally symmetric.

I guess a hammer and a form is the answer but my field is things that go round like lathes so I am not much help here.

A search for "Nibbling Machine" will show what you require.

These machines have various dies/cutters depending upon shapes required.
They will shear, slot, louver, bead, dish, planish etc.
The proper shaped planishing or dishing tools fitted to the machine, will give the shape you require with very smooth finish if used properly.
