This very very sharp cutting tool is a must for projects/sewing! It cuts so well that I need to learn how to manage it better. (I waste fabric because I am not used to it YET.) Very glad that I purchased it. Would recommend to everyone.

Sharpest, easiest to use. Cuts smoothly and most efficiently compared to my previous brand. Safety issue of blade use most appreciated.

I love this rotary cuter especially because the blade is covered until you use it. Kai has such fabulous products.

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.

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)
