I love these cutters...they are so easy to use...smooth cuts. I have used and owned many different kinds...but have never been happy with the results. I love how you can flip the blade attachment over so that you can cut circles on the outside rim.
I love the Curvy Cutter for making my circles. The one issue that prevents it from being a 5 star is that you MUST use a glass mat to really make it work properly, which is an additional expense and additional item taking up space on your scrap space. Otherwise, I have found that the circles cut very smooth and I love the variety of sizes that you can cut with the Curvy Cutter. When you use the cutter, I always find that it helps to use removable adhesive to hold the paper down on the glass mat and minimize slipping. Doesn't require too much pressure to cut the circle and the cutter is very easy to use in the track. Very good product!
