I like this particular rotary cutter because the blade stays hidden when its not in use. You don't have to remember to click a button up or down to hide the blade. When you go to cut, the blade is ready. And it has two settings for thin material (one layer) or thicker cuts (three or four layers)

I was looking forward to something superior. All the other Kai products have been so superior to competitors. I was disappointed. There is nothing wrong with the rotary cutter, but it cuts the as my 6 other rotary cutters. It does have a safety feature that is better than other rotary cutters. When you stop cutting, the blade is automatically sheathed, not need action. This is important!

This is a wonderful rotary cutter. I love the cushioned handle and the safety feature, which requires you add pressure to expose the blade. I looked for this rotary cutter for a year before I found out who made it and how to order them.

The rotary cutter provides a cushioned handle that is comfortable while cutting. There is no worry about the blade being exposed when not in use. overall a really great rotary cutter.

Love the ease with which the 45 mm rotary cutter works. It is smoothe and sharp. The fact that the blade works with pressure and then is protected when released has saved me from knicks on my fingers if I forget to close the blade. I am a very pleased customer. Also the service from Kai is great.
