I was in the quilt shop this last week and ran into a lady that just had to tell me what her favorite rotary cutter was ...I don't remember now what she said it was but I use a fiscar 45mm which she proceded to tell me was not a good one but I have used it for years and it works good if you ask me but I have never used any other ones so I really don't have anything to compare it to whats your favorite and why?....
