You might also be holding your cutter wrong - yes there is a correct way. Here is a link to Nancy Zimmerman - I looked out there and was surprised at how many of the examples aren't really correct, or like how I was shown. The two important things that I was taught was that 1) the ridges on top of the handle - your index finger should be on that and 2) the angle that you hold it. I have a lot of friends who when I showed them the angle got much better cutting results.
