I don't have much to add to what Ron N said. My lever has a tear-drop shaped end, that is, sphere + cone; it hugely increases the surface contact area between my hand and the handle of the lever, compared with a traditional handle. I grip the lever firmly in the palm of my hand, and the load/pressure on my hand seems to be distributed better than on any other lever I have used.
