Modeling a sword handle - Problem smoothing it out I am currently trying my first steps at modeling and currently trying out a sword.  I progressed well so far by modeling the blade and good part of the crossguard.  I decided to model half of the handle to have a good idea of the proportions I want.

Here is the work so far.
 



I am quite satisfied with the bottom part where the handle connects with the crossguard.  However, I would like the upper part to finish in a circle as the reference.  I still have not added no bevel, multiresolution or subdivision modifiers in these pics.  Nor any object shade smooth.

I have already experimented with the above modifiers but the results did not change nearly anything of the model.  No modifier seems to have an effect.  Why is this so and what can I do to smoot up the upper part of the handle?
You can use to sphere operation to make your selection in to sphere.



Once you start the operator, drag your mouse left and right to change the intensity.
