Great quality. Best I've used for cutting quilting fabric.

I have used two other name brands of scissors and rotary cutters and was satisfied with their products. While in a quilt shop, I saw the display of Kai products and asked about them because I was not familiar with the name Kai. I purchased a pair of scissors for cutting fabric. My goodness, there is a huge difference between what I had been using and the pair I just bought. I went online and purchased another pair of scissors ( just like the pair I had) and over a short time period added several different types of scissors that I use for sewing, quilting and machine embroidery. I purchased 2 rotary cutters and couldn’t believe the difference in how smooth the blade cuts fabric. The replacement blades are very easy to change out, just be very careful because the blades are extremely sharp. I will be a loyal customer with the Kai Company. I am extremely pleased with each product that I have purchased. Ordering online is quick and easy and shipping is free!

Any product Kai makes is superior! Sharp, clean cut, whether it be a rotary blade or scissors. Love them

These blades are far superior to the Olfa ones. They last a long time and are very sharp.

Thought this would be just another rotary blade that the company ad ertizes as great but it reaaly is the easiest to use and has stayed shape through a lot of cutting

The best rotor blades I have ever use

I cut and sew fabric almost every single day. I buy fabrics by the bolt! The first blade in my Kai-45 rotary cutter lasted several years. It's still sharp, but I probably ran over a pin and nicked the blade. My new replacement blade is like cutting through butter. I'm in love! I'll be putting a Kai blade in my rotary paper cutter as well.

After trying numerous cheap packages of 45mm cutting blades and getting just crap- I decided to go back to the Kai blades. Boy what a difference- from frustration to fun

Rotary blades don't last long, but I have to say that this blade has survived longer than any others I have used. I am very impressed. I should have know because I use Kai scissors almost exclusively. Another fine product from a great company.
