MSQC blades are the best!
MSQC is my all time, go to for my rotary blades. They seem to be the sharpest and last so much longer than blades I have bought elsewhere. If you can wait, you can get them for a great price when they go on sale. I aways buy the 45mm but I also have a 60mm rotary cutter and I am watching for a sale on those.
