I'm a rebar fan too. One of our members here (Xynadu) even has a video about making stout ass screwdrivers from rebar that're useful when you need to apply some real force.
I've used rebar for lots of things as well. What seems like a 100 years ago now I used to forge crowbars, tire irons, digging bars, and even had a pair of tongs that I made out of rebar. The problem with using rebar sometimes though is you cannot ever be sure of the quality of steel in it, since most of it is made out of recycled steel the mills sometimes don't always monitor the grades of materials that go into the cauldron to be melted down as closely as they would for other steel shapes.
I've encountered some that would snap into when trying to bend like a peppermint stick and some that would bend like saltwater Taffy
