So far the majority likes the 45 mm, with some liking the 60 (those of us who aren't afraid of it - I am!!!) and some, like me, liking the 28 mm. Olfa and Martelli seem to be the top brands, at least so far. Since so many of you like the 45 mm cutter, I'll have to try mine again and see if I can get used to it. Thanks for answering my questions. I am always curious as to what other tools quilters are using and why.
