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!!!!

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.

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

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.
