i brought this to do some cutting with the new Graphic 45 'once upon a springtime' collection and it does the job perfectly. i get a clean cut every time i use it and i love how it comes with the extra blades rather than having to worry about trying to find some.
I love this craft knife. It is precise, cheap and has replacement blades. I really recommend it.
I suppose I might be asking for too much in a craft knife, but I thougth it would be sharper at the tip, and on the blade. I was trying to cut out a circle about an inch around, and I had to run over the paper serveral times, and it still cam out jagged and rough. Maybe there is not knife that could cut a circle that small, or maybe it's my technique, but so far, it's not what I wanted.
