Well, just to reiterate my position vis-a-vis modern steel and antique steel (let's say before 1850):
1. Our ancestors did not have the chemistry to know what trace elements were going into their steel, or even controlling the amount of carbon in it beyond relatively wide limits. They didn't even know it was carbon that allowed the steel to harden.
2. They could not make good steel consistently, although they could recognize good steel after they had made it.
3. Over the past 150 years, we've gained a pretty good knowledge of the chemistry of steel, the hardening process, and the micro structure of the steel. This knowledge has been used to tailor steel to specific uses, including woodworking (chisels, plane blades, power saws, etc.)
4. Essentially all users of steel have moved to modern steels for the advantages the modern steel has.
5. It would be sad indeed if we had not made significant improvements in steel for specific uses over that period of time.
6. Just because something is old, it does not mean that it is better, or that our ancestors had some magic that has been lost to modern time.
None of this is to imply that antique steel cannot be used in woodworking. It's obvious that our ancestors used that steel and produced some outstanding furniture. You simply have to know the characteristics and limitations of the steel and work within that performance envelope. The same is true for modern steel. It's just that the performance envelope of modern steel might be larger than the performance envelope of antique steel.

[A good example of improvements in steel is the razor. A modern razor can be used many, many times and still give a very close, comfortable shave, with no maintenance except washing the crud off the blades. Compare that to the old Gillette "Blue Blades" (for those old enough to remember them), or a straight razor. With a Blue Blade, you were lucky to get two shaves before it was too uncomfortable to use (felt like it was pulling the hair out). And straight razors are honed before every use.]

Go into the world and do well. But more importantly, go into the world and do good.
