    Now that I can see the larger picture, I understand what you are asking.
    Given the machine marks, that is a 3D cut, with the sole facing up. (or a 5 axis machine)

    I am not sure why the sole would need a convex surface, other than "to be different /cool" or for weight specs.
    OR
    The convex (3d) shape could be custom tailored to change the balance point from face/ back, or from heel to toe.

    Outside of that, I haven't a clue.

    Top level golfers a weird bunch and not the average man.
    Those underneath will spend lots of money thinking the magic will come into their hands with this or that.

    I understand the 2 - 4° angle of the bottom of the putter to the face (loft), but I have not seen much in the way of a rounded bottom.
    Do you mean the convex shape is from heel to toe, or from face to back?

    If heel to toe, side of endmill. If face to back, then 3D of form tool. My guess anyway.

    They are curved both front to back and heel to toe.

    Can you feel them with your fingernail? At first I thought it was marks from a rubber wheel behind a grinding belt but the larger picture sure looks like machine marks. The convexnessity from “front to back” (as opposed to “heel to toe”) looks very slight (meaning it sure looks flat to me, but if you say it’s curved then it must be) so maybe it is just a rough surface finish from a ball em doing some mild 3D contouring.
