Every good carpenter and DIY'er needs a solid, dependable circular saw in their tool collection.  The unbelievable adaptability of the circular saw allows it to do an awesome diversity of things, that makes it among the most desired tools in most wood working shops.  The flexibility to adapt the depth and angle of your cut makes lots of things possible. 
 
You'll find 2 different kindsof circular saws presently: in-line circular saws and worm-drive circular saws.  The main difference between them is the positioning of the motor, that also greatly affects the amount of torque given.  With a worm-drive saw, the motor is placed parallel to the blade.  This style permits the motor to transfer a large amount of power to the blade, allowing it to cut through all types of substances, from wood to metal.  Generally, most pro craftsmen use worm-drive saws on account of the additional power and versatility.  Nevertheless, the increased torque also ensures they are  more dangerous than in-line saws.  For that reason, I believe that worm-drive saws should only be used by professionals.  Check out some more information on that topic here:

For standard DIY projects, an in-line (or sidewinder) saw is a terrific choice.  Though they have less power than a worm-drive saw, most in-line saws would have no problem managing almost any task you can throw at it, besides serious industrial construction.  In addition, they're just safer, lighter and generally easier to use.  Make sure the circular saw you choose features an electronic brake.  This feature triggers the flow of electricity to be reversed when you release the trigger, forcing the blade to stop promptly.  This is an important and useful safety feature. 

If portability is significant to you, you will want to think about a cordless circular saw.  This will allow you to use them almost anywhere, without needing a generator and long extension cords.  There are actually some drawbacks to cordless circular saws: they produce less torque, and that you're constrained by the runtime of the battery pack .  You are able to purchase more battery packs to broaden the time you can work, but you need to remember to have them all fully charged and ready to go, which can be inconvenient.

Be sure to think about the kind of work you'll be performing before getting any power tool.  This is particularly correct with circular saws.  If you change blades fairly regularly, getting one with a quick-change option could save you a lot of time in the future.  If you require deep cuts, you'll need a saw with a blade size big enough to meet your demands.  Also, do not forget to read some circular saw reviews prior to making your purchase to guarantee you purchase the best circular saw you possibly can.

Like I said at the beginning, every craftsmen and hobby wood-worker needs a strong, safe circular saw in their tool collection.  The astonishing usefulness of the circular saw permits it to do an incredible variety of jobs, which makes it amongst the most desired tools around most wood-working shops.  The flexibility to adjust the depth and angle of your cut makes all kinds of things possible.
