I'm not a representative of Stack Exchange, and this is hearsay from what I know. I can find out more, but I wanted to get you an answer.
This is an unfortunate scenario that I'd love to see righted, but it's difficult right now. I'm not aware of the current situation, but ultimately, several years ago, the USPTO came to Stack Exchange and asked for this site to be created. In a joint venture with Google, SE made the site in the interest of crowd-sourcing the search for prior art on overly broad patents and applications.
In that process, Google installed the button you used on their Google Patents pages with the word "Discuss" on it.
And here we are now.
Yes, that button is labelled poorly. But the general consensus has been that it isn't worth pursuing to make better. I, personally, disagree with this a little. I hate to think well-intentioned people are coming here with the wrong expectations about what this is. But that's what it is: we're a Q&A site with the goal of helping people to understand the patent process, and to find prior art for overly broad patents and applications.
In your particular case, I definitely respect what you're doing: I agree that preserving historical articles like this is of the utmost importance. The issue with using Stack Exchange in this particular way for this, aside from that it's outside of our scope, is that preserved data is only as good as it is findable. And people won't look here. Honestly, I'd suggest finding or creating a relevant Wikipedia article (or equivalent) on either the patent or the knife, and adding the information there. That's a good place for things like this.
We do support some discussions, via our chat feature, but I'm not sure that would serve your purpose with this.
We also support information-preservation through self-answering questions, but unfortunately I'm not sure this is a good candidate, because licensing and production questions are each off-topic for us. So I'd really go the Wikipedia route if I were you.
Sorry for the confusion.
