A better letter opener has been built! It does not fit inside a couch as readily as the one I despaired of finding and therefore bought the new kind. The old did well for King Arthur but had to be dulled for home use. The new blade is even sharper but encased safely inside a little blue whale that holds it at the best angle to slash right along the edge and out the other end in one stroke with no chewing guided by a proboscis that fits right into the little corner of the flap that never gets licked.
