I purchased the Carl Rotary Trimmer last year when I began to make homemade calendars. I needed a paper cutter and the description of this trimmer made it sound perfect for my projects. I have been very pleased with this trimmer. Since I bought it, it has helped me with any cutting project that I need and it's so wonderful to use instead of scissors, I get a perfect, straight line every time. After a year of occasional use, the blade is still sharp and I've had no problems with it, at all.
