Most good sawzall blades are Bi-Metal blades.

You are correct, sir.

The cobalt is in the teeth that are Electron Beam Welded to the spring
steel body of the blade.

Hope the spring steel doesn't present a problem, I considered heating the
blades to take out any tempering, but I probably won't have time. These
pieces were supposed to go out this evening. I hate it, but that's what
happens when they send us home for a week and a half.

Thank you Ernie for your answers to my question,
