Actually, more than 1 national teacher has stated this isn't necessary anymore. It was necessary when the qualtiy of paper wasn't so goo and it had more 'other stuff' in it that could dull the scissors.
I just use the scissors that are close and haven't had a problem.
Of course, I do have a very old set of specialty dressmaker shears that are for sewing projects only. I don't even use them for quilting. They are that old.
