Over the years, I have developed quite a reputation with a sawzall. I have told people, “It’s not that I am good with a sawzall, it’s that I’m very, very good with a sawzall!” I keep two reciprocating saws in my truck. One corded and one battery operated. I have been accused of putting the blade is backwards. Anyone who really knows how to use a sawzall puts the blade in backwards. You get a better angle on the work piece when you are up against a flat surface. I also use 12” blades. You can get even closer to the work surface with the long blade. It allows you to cut through larger piece and 5” to 7” stud walls.
I have even done trim work with my sawzall. The key is having a sharp tip. You place the blade as flat as you can against the work piece, then watch the tip. Start the variable speed saw slowly until the tip begins to grip into the wood. Then bring the blade down on your line and increase the speed. This particularly helpful when cutting base in place for a new door opening. I keep several sharp blades, with course and fine teeth, in my truck. I can keep the saw and blade tight against a sheetrock wall, with only the tip penetrating the sheetrock and cut out an opening without cutting the studs, wires, or pipes with.
With the long blade, you can even cut a straight line while bending the blade to offset the saw. Sometimes, you do not have the room in front of the work piece to position the saw without bending it.
The sawzall gets almost daily use on my projects.
