Saw-cut joints are created by using a circular saw with a diamond blade to cut the concrete into segments. The segments are then separated by sawing through the connecting mortar joints. Saw-cutting is generally used to make control joints, which are placed in concrete slabs to help control cracking. Saw-cutting may also be used in combination with other methods, such as coring or hydraulic fracturing, to produce more effective control joints.

Saw cutting is generally the most efficient way to cut concrete, but it is not always necessary. There are a few ways to cut concrete without a saw. One is to use an angle grinder with a diamond blade. Another is to use a demolition hammer or jackhammer. Finally, you can use a chisel and hammer. Each of these methods has its own drawbacks and limitations, so it's usually best to use a saw if you can.
