Your average foundation is made from concrete and rebar. The rebar is inside the concrete and reinforces it so it can support the weight of your home.
The rebar gets cut, bent and tied together to form a cage like structure. There are several ways to cut rebar when prepping for a pour.
First are expensive fancy pneumatic or hydraulic cutters.
They work good, but are dang expensive. Some have better cutting speed than others.
Here’s another method, using a manual rebar cutter.
Those work really well too. Way cheaper, and they can go dang fast. The most common size rebar is #4 bar, and a manual cutter goes through that just fine but it does take some muscle.
Lastly there is the good old chop saw.
These cut bar like butter. It takes almost no muscle to use. The down side is they throw a lot of sparks and make a lot of noise.
I usually use the last two methods. Manual cutter for #5 bar and smaller, chop saw for bigger stuff. I’ve used the hydraulic cutters on a few jobs because they were already there, but I sure wouldn’t go buy one $$$$.…
