Out of the box it didn't cut square. I tried several sheets or varying thickness, being very careful to aline the paper with the grid marks; I only got a square cut 25% of the time. Also, even the thinner paper did not cut easily. I understood that some pressure needed to be applied to push the blade through, however, again only 25% of the cuts made were clean without the "fuzz". I took it back the next day and got the other style blade from Fiskars and have had no trouble.
