Links 1, 3, 4, 5: all fairly recent that failed to sell for 1 scrap. Hell, one's just 4 hours old. The oldest is 1 week, which is reasonable.

Link 2, "any strange weapon". Not really a proof that these sell for one craft weapon, even if it hasn't sold. Still recent trade.

While I'm inclined to agree, I sold a Can Opener myself for a scrap within a day of listing, while it was about a month+ ago. While you've kinda demonstrated that nobody will buy for 1 scrap, show people selling for a weapon and I'll upvote.
