You probably can. Depends what's going on in the steel though. With a saw blade you are really making a guess as to the type of steel and to the hardening process. Pays to anneal and normalise first though. Much nicer to work with a softer piece of steel as well and basic hc steel is cheap enough that you aren't saving much by re using the old stuff
