Double dilemma: my window-opening project needs a Sawzal; my door-locking project needs a jig saw. And I'm not having a "I want to go out and rent a saw" kind of day. So do I rent a Sawzal, butcher the door and window, and call it a day, or do I rent a jig saw, do a civilised job on the door, and keep chiseling the caulk off the window?
