When the hide away ruler is used it can accomodate the entire 12 x 12 cardstock. The cut is clean and the blade is sharp. It comes with an extra blade which is nice.
A must-have item for scrapbookers. But you'll need replacement blades, because they loose their sharpness quite quickly with regular use. I ended up needing to use an emory board to help finish up the cutting, after some time. But it doesn't bother me.
