Anyone have a clue why I can't get my cutter back together after I took it apart to change the blade.. I finished cutting all my squares, and was going to cut extra's to send, but thought the blade wasn't as sharp as it could be, so I took it apart.. It does not want to go back together.. It is an Olfa with the quick release. You are supposed to slide the piece, and then slide it back. It's not staying tight when I moved it back.. Ughhhh
