Gidon, I'm glad you don't mind.
I cut the handle in two and made a component of one half. Then I copied and mirrored that half to make the opposite end. Since they are both instances of the same component, SU is only "remembering" half the geometry of the whole thing. this lets you get away with higher segment counts in curvy stuff without bloating the file size.
There's another benefit to this as well. If you decide to edit the shape of the handle in some way, you need only edit one end. The other gets done at the same time.
FWIW, there was some unneeded geometry inside the center portion of the handle which I also got rid of. I didn't check at the opposite end.
FWIW, here is an example of some detailed curves in SketchUp. The fronts and backs of these pipe boxes are split down the middle so that the left half and right half are mirrored instances of the same component. The front components are different on the left pipe box than the right so they are different components. There's a radius on the edge of the drawer face and the joinery is drawn throughout. Even with the material applied the file size for just the two front boxes was only 233Kb. In the attached image, there are ten of each and the file saves out at 259Kb All because I used components and split the symmetrical ones.

Oh, and one other thing. Another side benefit of spliting the panels here, is that I get book matched grain automatically. Not really appropriate on these pipe boxes but for something like a veneered door panel it might be.
