There are several types of circular saws that have in the market, as a compact circular saw it also known mini circular saw.
To get the headline's answer, firstly, you will need to know the basic features of a circular saw.
A powerful high-speed motor drives the blade of a circular saw – generally, its RPM is 5,000 – 5,300. Most of the circular saw's motor is powered by electricity. Some models are powered with the lithium-ion battery too.
Circular saw blades are different in type, and the TPI of each blade type differentiates them. More teeth in a circular saw blade mean more precise cutting.
7 ¼” is the standard size of a circular saw blade. However, the small and larger sized blade is also available. Other important things are the gullets and the gaps between the teeth. Both are responsible for cleaning wood and wood chips while cutting a wood piece.
Circular saws come with safety features which may ensure safety of you.But it may do harm to you if it is not handled properly. The blade guard works as the safety feature of a circular saw. It consists of a few parts.

Some model of circular saw comes with an extended safety feature. They contain a switch that needs to be released before the blade starts moving.
It is a piece of long metal opposite the handle with the leading edge of the saw and placed perpendicularly to the blade. It rests on the cutting surface while cutting a wood piece and confirms cutting following a straight line.
The good news is the base plate is adjustable according to a different thickness, and you can tilt it to a 45° angle while bevel cutting.
Newer circular saw models come with laser guides which can ensure that the cutting will follow the straight lines.
