Here is a Q and A from a blacksmithing website on rebar steel.
Is rebar good for tool making ? Can it be hardened ?

Rebar: Mark, There are three different grades of rebar with different hardenabilities. Then there is OLD rebar which is generally non-specific as to specs or quality. No version is designed to be used as a tool steel. It IS done but I don't recommend it. You are much better off to use spring steel or recyle old tools
Mild Steel, Normal Strength or Ordinary Weldable Steel
These trade terms are often used interchangeably to describe standard carbon steels used for structural purposes, a typical example being AS3679 grade 250 or grade 300.
The term ‘mild steel’ is also applied commercially to carbon steels not covered by standard specifications. Carbon content of this steel may vary from quite low levels up to approximately 0.3%. Generally, commercial ‘mild steel’ can be expected to be readily weldable and have reasonable cold bending properties but to specify ‘mild steel’ is technically inappropriate and should not be used as a term in engineering.
So with a carbon content of 0.3% a smith would not be able to harden a blade making it very easy to bend when applying lateral force.
