KLO I use a rotary cutter, the small one would be better but there are some rules to this deal. First, do not let anyone sitting next or in front of you with in a foot or so. No chatting as you are doing this. As you must know the dull blade can be more of a damage than the sharp ones but either way, one needs to be super careful. Then, you get to pull out the stitches one by one but by then, you are ready to sew again. When in our group, I will say don't do this as I am doing but I still do.
