I like the martelli. They have them for both right and left handed people.

What I have found works best is to use different cutters in the same cutting 'session'. I cut with a fiskars stick type, then use the martelli, then back to the fiskars. I find that if I don't hold my hand in the exact same position it helps a lot.
