The reciprocating saw (figure A) has a blade that moves back and forth. It is a very useful tool for cutting through thick wood as well as wall studs. You can also use a reciprocating hacksaw blade to cut through the nails or screws holding drywall to the studs. Reciprocating saws are available in both corded and cordless models.
The jigsaw (figure B) works in the same manner as the reciprocating saw, with a blade that moves back and forth. Jigsaws are good for cutting out fine details and work well for projects around the house, crafts and hobbies. Jigsaw blades can be delicate, so don't try to force a jigsaw to cut through tough wood; it takes less time in the long run to use one blade at a steady pace than it would to cut quickly but replace the blade three times.
The circular saw (figure C) can use several different blades. It be used either as a demolition tool or as a tool for fine carpentry.
