  1. The Best 5 Star Review

    Posted by on Mar 18th 2018

    The best rotor blades I have ever use

  2. customer for life 5 Star Review

    Posted by on Mar 15th 2018

    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

  4. Longer lasting 5 Star Review

    Posted by on Jan 10th 2018

    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.

    The blade is so sharp, I noted on the handle when I installed it. Trust me, it lasted at least twice as long as any other brand I have used. LOVE them!!

    I have been sewing for years. I have tried several different brands of scissors and rotary cutters. I have purchased, from the Kai Company, several different types of scissors as well as the rotary cutter. I will never use anything except Kai products. products! Excellent products!!!!

  9. Thank You Kai 5 Star Review

    Posted by on Jul 16th 2017

    I have been looking for these blades for ages but they don't seem to be in the shops I go to. My Kai rotary cutter is the my first and my favourite cutter so I was pleased to be able to buy replacement blades at last

    The sharpness of this blade is what I was always looking for in the U**fa brand but never got. I can tell this blade will stay sharper longer, too. Makes the cutting part of sewing something to look forward to. February I will be ordering the pinking rotary cutter for certain. Thanks Kai Scissors - your products are truly the best.
