I'd have to watch how you created them to really know how they got the fish hook shape to them, but it's not just a rendering glitch that's a hook in the shape of the curves those surfaces were extruded from.

It looks like you've got some of the curves in your file there, it's difficult to see the hook just by glancing at them but if you turn on the curve control points with Edit > Show pts and move the ones near the bottom you can then see the hook type arrangement - the points do not go in an incremental order, the ending control point of the curve is "back tracking" back along the reverse direction:
