Prior to the update just now, the Throwing Pick was written with a Chronology header. However, shouldn't they be written (as well as other "universal" items) with a Usage header, since any player can use them?
Weapon chronologies were created mostly for the very important weapons like the Dark Repulser, Blue Rose Sword, Elucidator, Excaliber, etc. I suppose it doesn't fit well with the generic and minor though. I can't think of any clean ideas to solve it but there are a few messy ones.
I can't see a good way of doing that other then creating another category called minor weapons and having those go with usage over chronology, but then what determines minor weapons and the like. Plus it creates another problem of having two type weapon pages which is confusing in itself. Chronology is the more informative form so I would rather pick that over usage.
Chronology tends to be more filled with junk content (I removed around 1,800 bytes of completely unnecessary content after converting its chronology into usage and saving the actually useful content as trivia) over usage which simply states where the item was used and why. Of course, certain details which are not that irrelevant are also lost. There's also the fact that chronology implies that the item is unique, even though certain items like Throwing Picks and weapons like Anneal Blade are used by multiple players in unrelated instances.
When we can avoid them, yes. When there's no other suitable option, a double standard is better than using a system that is unsuitable for the page. For example, for skill pages, I pretty much have to improvise based on what the skill has. For some skills I can't squeeze out a mechanics section (either because of a lack of information, or because the skill is too straight forward), while others have certain mechanics that should be explained on the page. Some skills have a variety of features, while most others only have one - making a list for just 1 feature is silly.
So, either we decide on 1 system to use for both types, or make the pages differently based on whether the weapon/item is unique or not. Either way, we need to make a decision instead of dragging this on till next year.
