Luclin-era weapons looking like Sheer Blades

[Drawde]

I've noticed that a lot of weapons, mostly ones added around the time of the Luclin expansion, have
the appearance of a "Sheer Blade" (the Iksar hook-ended sword thing) - I can't remember the exact appearance ID, but
I think it was 100. This is certainly an error in the DB, many of these weapons are blunt ones or spears! Those that
don't look like sheer blades usually have the "Spiked Staff" appearance which also looks to be erroneous in many cases.
Would it be worth manually correcting this, or simply re-gathering the item data?
