Every good carpenter and DIY'er needs a durable, safe circular saw in their tool collection.  The unbelievable overall flexibility of the circular saw enables it to do an amazing diversity of jobs, turning it into among the most widely used tools in most woodworking shops.  The flexibility to change the depth and angle of your cut makes all sorts of things possible. 
 
There is 2 standard designsof circular saws currently available: in-line circular saws and worm-drive circular saws.  The big difference between them is the positioning of the motor, which drastically influences the amount of torque available.  With a worm-drive saw, the motor is mounted parallel to the blade.  This style permits the motor to transfer a large amount of power to the blade, allowing it to cut through a variety of materials, from wood to concrete.  Generally speaking, most pro tradesmen use worm-drive saws simply because of the additional power and versatility.  However, the increased power also ensures they are much more dangerous than in-line saws.  Due to this, it is my opinion that worm-drive saws really should only be used by experts.

For standard DIY work, an in-line (or sidewinder) saw is a wonderful choice.  In spite of offering less power than a worm-drive saw, most in-line saws will have no issue doing almost any job you could throw at it, short of large industrial construction.  On top of that, they are just plain safer, lighter and generally easier to use.  Check to be sure the circular saw you pick out has an electronic brake.  This feature causes the flow of electricity to be reversed as soon as you release the trigger, forcing the blade to stop promptly.  This is a very important and handy safety feature. 

If transportability is necessary to you, you may want to consider a cordless circular saw.  This will allow you to use them almost anywhere, without needing a generator and large extension cords.  You'll find a couple drawbacks to battery powered circular saws: they offer less torque than their 120V alternatives, and that you're constrained by the runtime of the battery pack .  It is possible to purchase more batteries to lengthen your work time, though you will need to remember to check that they they've been fully charged, which is often bothersome.

Make sure you consider the kind of work you may be doing before deciding on any kind of power tool.  This is particularly the truth with circular saws.  If you need to switch blades on a regular basis, buying one with a quick-change system could save you a lot of time in the future.  If you need deep cuts, you need a saw with a blade depth big enough to meet your requirements.  In addition, be sure you check out some circular saw reviews prior to you making your purchase to make sure that you purchase the best circular saw you can.

As I said at the beginning, every craftsmen and DIY'er needs a strong, dependable circular saw in their tool collection.  The unbelievable versatility of the circular saw permits it to do an astonishing variety of chores, which makes it amongst the most desired tools in most wood working shops.  The option to adapt the depth and angle of your cut opens up the door to a lot of possibilities.
