There are actually a number of different rebar grades. Most rebar used in construction is the cheapest possible rebar available, however there are many varieties that are engineered for specific jobs and conditions and load requirements. Some rebar is soft, some is springy, some is hard, some is weldable, some is non fusible, some is corrosion resistant (for use around sea water or in buildings like oil refineries or power plants). So yeah, if they have the right rebar it will harden. The concern that I have is that even with rebar that can be hardened it's not common to have a carbon content above 0.55 percent. It's essentially agricultural steel. So ideal for tiller blades, axes, and hammers (or holding a building foundation together) but not ideal for knives (esp. high performance kitchen knives). It would definitely make an acceptable knife that is a very tough, heavy use farm or camp knife, but you'll be sharpening it a lot.
That looks super cool :3
Brother ive made manny rebar knives and some of them held better edges than any store bought knife ive tried. Keep it up!
Make a goodendah
Medeval club with a spike stickin out the top
But it looks very nice
I don't think rebar will harden when quenched
