We have one stick handled 45 that we never use - I just find it too awkward to cut with. We have two Olfa ergonomic 45's and I use them quite a but. We have one Olfa ergonomic 60 that I use when cutting several layers. We also have a Martelli 45 that I use less often than the Olfa. I love it and it is easier to use, but I just pick up the Olfa out of habit.
