Hi, glad to help!
I've used olfa's blades for over 20 years but recently a few of my friends were raving about a new rotary blade called improved cut.
I was curious about what they were going on about so I tried them and was very impressed.
I don't think we are meant to add links here but I'll try anyway if you want to check them out!

Hope that helped!
