Jig Saw
Clean Cut Techniques
Depending on how pristine of a finished product you're looking for will determine a few things. First take note of the setting on the side, usually with numbers 0-3. This is the aggressiveness of the blade motion. 0 will keep your blade straight with no rock. This setting is for the cleanest cut, but also the slowest. 3 will have an aggressive rock, where the bottom of the blade kicks out on each stroke.
So, your looking for the cleanest cut possible. This takes more time, so only do it if you really need to. Instead of marking your cut line on your material, you'll run a line of painter's tape. Now, put your marks on the tape and draw your cut line on the tape. With this method you wont chip your material. If you really want to get crazy you can tape the bottom of your Jigsaw tool's plate. You can also buy wider tape and just put two pieces next to each other.

Arc Cuts
One of the more unique abilities of Saber Saws is their ability to make round cuts. A Saber Saw is the family in which Jig Saws and Reciprocating Saws both belong. It's simply a saw with a straight blade, attached on one side to a reciprocating motor. When you're making curved cuts with your Jigsaw, make sure to rotate the back of the saw. Do this motion slowly and don't be afraid to back up and take a new angle. Remember, you don't have to cut on the line perfect first try, just cut less material than you need to, rather than too much.
Plunge Cuts
You can plunge with a jigsaw by putting the front edge of the plate on your material and slowly pivoting the blade into the board. I wont say you should NEVER do this, but don't. What you want to do is drill a hole with a bit just larger than your blade. This will serve as a starting point for your cut. You can use a larger bit if you want, it just has to be wider than your blade.
