I use the rotary blades all the time and the Kai 5045 Rotary cutter. They are both awesome products and better than any I have used.

These are the best Rotary Cutter Blades ever.
I have blades from other companies and none of them compare to Kai Scissors Rotary Blades.

This rotary cutter is amazing. The blades are sharp and cut evenly and quickly. The cutter itself is nice to hold. Just the right balance.

Had bought the rotary cutter a few years back and thought I could use any rotary blade on it when needed, sadly Kia rotary blades have a slightly different shape on the inner attachment. Kia ships very quickly so I was back using my rottary cutter in no time.

I shouldn't be surprised by how sharp these blades knowing they are Kai but I was still impressed with how Sharp they are.

This product is great. I needed a new blade for my Kai rotary cutter and this blade came in quickly. It was nice and sharp and cuts through fabric with ease.

I purchased my first Kai rotary cutter several years ago and it opened a whole new world of cutting fabric. It was such a pleasure to use giving nice clean edges and it was such a time saver. After many years, the blade needed to be replaced and I ordered a replacement online. I received it very quickly and the price was very reasonable as well. Unfortunately, the new blade didn't seem to give as crisp a cut. A couple weeks later I received an email asking if I would review the product. It occurred to me that I couldn't give a review without first contacting Kai to tell them about the problem I was having with the blade. They responded immediately and were so apologetic and were ready to replace my blade or refund my money without hesitation. I asked a friend to look at the blade to see if he could see a problem and he said he could see a couple very tiny nicks in the blade and that would account for the little snags I was getting in cutting. I relayed the into to Kai and got a second email from the Natl Sales Mngr apologizing for the problem and again, offering to send out new blades immediately. It was such a minor problem to experience, in particular during this time when the Pandemic is in the forefront of many minds and lives. I agreed to have them send a replacement blade but instead they sent 5 replacement blades!!! I am bowled over by the kind attitudes of each person I had interactions with (Kris and Jeff) and my new blade is just perfect! Thank you SO much Kai for a great product and terrific customer service.
