My instinct was to cringe when I saw what steel he had collected, pry bars and what not. Then when they show him doing the forging, it looked like a bar of some steel. Who knows what it really was? But then I immediately go to thinking, "Good for him." He more than likely doesn't know all the intricacies we know. He likely doesn't know the metallurgy that some people here. But he used what he had, and made two decent looking knives. And from what I recall, they were not thick tire iron knives. They had a thin profile to them, if memory serves me right.
Getting critical about his heat treat.....he said magnetic is the temp. I hear that quite a bit on knife forums. And we all know that non magnetic is not hot enough. Not only that, he took FOREVER to go from magnet not sticking to his quench bucket....whatever his quenching medium was. If he would have gone past non magnetic a touch, and have his quench bucket right there ready to go, I bet he would have gotten a much better result.
He actually took the time to make a brass bolster. Something I would not have done, so he went further than what I would have.
Again, all in all, I think he did a good job.
