    I am enjoying my new rotary cutter. It has a nice handle and easy to use. Just press down and blade comes out. Finish up and the blade retracts, very safe.

  6. So comfortable 5 Star Review

    Very comfortable

  7. The blade stays hidden 5 Star Review

    Posted by on Oct 11th 2017

    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)

  8. No better than other rotary cutters 4 Star Review

    Posted by on Jul 31st 2016

    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!

  9. Greatest rotary cutter 5 Star Review

    Posted by on Jul 8th 2016

    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.

  10. Great rotary cutter 4 Star Review

    Posted by on Apr 25th 2016

    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.
