Pam, you got a great deal and that will keep you for a long time. I want the hoopla on the Harbor Freight blades to die down and also to see how people really like them. I'm worried those blades might be TOO good and shred some mats. I'll wait and see. In the meantime, you know Olfa blades are tried and true and $1.60 per blade is not too shabby!
