Have had one of KAI rotary cutters for many, many years but when lent to someone they unfortunately damaged the little plastic piece that holds the blade in position (it was quite old). So, as I liked it so much, I purchased 2 (along with spare blades) so I have a back-up. Ergonomic handle ensures ease of use with little pressure required.

I have had a popular brand rotary cutter for over 20 years and it never, ever cut a completely clean line with or without a lot of pressure being applied. A friend of mine recently suggested I purchase a Kai rotary cutter and blades, and I am so happy I followed her advice! It is the best rotary cutter I have ever used hands down!!! You do not have to apply a lot of pressure and the blade cuts through clean and smooth. I can obtain an accurate cut every time. Thanks Kai for a great cutting tool that has made my cutting and sewing life enjoyable!!!

I probably own 12-15 rotary cutters. I think this is my new favorite. It is ergonomically very comfortable. I do a lot of rotary cutting because I make handbags, totes, etc. This is not heavy. The curve makes it very comfortable and the blade has lasted an unusually long time. I would highly recommend.
