Thanks. I am still a bit of a novice and the blade that came with my cutter didn't cut very well but since it was new I just thought that was how it was suppose to be. Finally, after about 6 months I bought a new blade and it worked much better. It has been another 6 months so I guess I need a new one now anyway. When my blade was sharp, I don't remember ever needing to cut through a really thick stack so I can't remember if it worked good or not. But, from both of you, I gather it will be fine as long as I get a good sharp one. thanks.
