The difficulty I'd have with a cutter like that is the offset of the blade. You have to offset the position of the straightedge the proper amount to make an accurate cut.
I use single bevel knives. That way, I can put the straightedge on the line and put the flat of the knife against the straightedge.
The negative to the single bevel knives is that you have to sharpen them - they aren't throw away blades. But I don't find that too difficult.
