  1. You get what you pay for! 5 Star Review

    Posted by on Jan 30th 2018

    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

  2. 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!!!!

  7. 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.

  9. Best 45MM rotary blade 5 Star Review

    Posted by on Oct 23rd 2016

    Kai 45MM rotary blades are the sharpest blades I have ever purchased. Far superior to the ones available in the sewing center.

  10. So sharp! 5 Star Review

    Posted by on May 19th 2016

    These are super sharp and seem sturdier than the Olfa ones I've used in the past. I haven't cut much yet so can't speak to their holding power, but I hear that these stay sharp longer than other blades.
