Subdivision, rounded edges problem I'm trying to create a door handle with smooth rounded edges, like this:



I'm having a problem when trying to bevel or apply a subdivision surface modifier, mainly that I'm not able to correctly apply loop cuts to sort out the modifier. 

Also bevelling the edges both with a modifier and with ctrl+b isnt having the desired effect, sometimes it doesnt even give me the option to bevel.

Here are some pictures of the nasty creases i get across some edges after i apply the subdivision surface modifier and add loop cuts
It looks like you have some duplicate vertices and/or faces in your model. The first thing to do should be to remove your duplicate vertices. In Edit Mode, select the entire mesh by pressing A. Then, press W and click "Remove Doubles". This should help to clean things up. If this doesn't fix it, make sure that you are using the Bevel Modifier before the SubSurf modifier. This will prevent your SubSurf modifier from destroying your topology. Since you have a cylinder, you want the "curved" faces sub-surfed, but not beveled. To do this, set the Bevel Modifier limit method to "Angle" and set the angle to something greater than the angle formed between two of the cylinders sides (probably about 15 degrees). To get a cleaner bevel at sharp corners, set the width method to "Width". To get the curved effect in your reference image, increase the Bevel Segments and Profile. It should look like this:
