The Fiskars blades are committing suicide!

Well, between all the cutting for the invitations and the guestbook...I've went through 3 blades...2 brand spankin' new! ARGH! They're not the cheapest thing in the world, and for some reason, Wal-Mart no longer carries them! At least not the one I just went to....so I guess I'll have to wait until I can get to Michael's to get more, but here's what I've got so far. 120 RSVPS are done...not sure on the rest...I had to toss a couple of the smallest ones as I cut words off by mistake. OOPS! I will need more paper, but I'm not even sure how many invitations to make right now. SIGH So tired of cutting....anyone else think that the Fiskars paper cutter cuts at a slight angle?!
