Glennjannie - I love those Axe blades for demolition. They last a long time and cut just about anything. Unfortunately I need to disagree. Using a reciprocating saw in this situation can be an issue. First off - Someone less experienced with a recip saw will have a hard time starting the plunge cut. Also, we have all seen newbies with a recip saw shaking hard because they are not leaning into it or holding tight. This shaking can do really bad things to a plaster wall. (we don't even know if its actually is plaster).
I think the circular saw would be a much better choice for a homeowner in this case. Or, even better, a utility knife. It costs 99c and won't make as big of a mess.
