What tool do you use to cut through concrete?
Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it’s best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.
Can I cut concrete with a circular saw?

How do you cut concrete by hand?
Use your dominant hand to grip the back handle and push the blade forward and backward. Begin cutting at the edge of the concrete and slowly follow the chalk line. Don’t press the blade into the ground—let the weight of the blade and saw do the work. Remove the blade every 30 to 45 seconds to avoid overheating.
