I guess any tool massed produced is bound to have a dud ever so often. I have other Olfa's that are years old and still working just fine. I have too many cutters, all brands. Last count my basket had 21 cutters not counting the ones in travel totes. In my defense I use to get one every gift giving occasion from family, win at door prizes, use to be they were sold at high discounts from reps when doing demos at quilt shops. Even have a few that were hand outs at quit big quilt shows years ago. Remember getting the hera markers in quilt ad mailings? And the Seam Jumper?
