Query: Replacement Blades 2-pak

I haven't had to use these yet but I would assume they are the same as the one that came with my Fiskars Rotary Cutter. I didn't want to be left with no cutter in the middle of a big job, so having these extras on hand assures that my job will be completed without worry about having to order a replacement cutter. I think it's good insurance to have an extra blade or two!
