The solution to this would be setting the transparency on these items’ handles to their transparency level stated on the script. (0.7 on Ghostwalker and 0.5 on Icedagger)
This can be seen working on the item Ghostfire Sword, which has a transparency level of 0.25 on it’s handle.
The gears you listed in your report have a transparency on the handle as intended, but don’t appear transparent in 3D view. The ones I’ve reported here have none at all, but are supposed to. Both about transparent items, but different issues!
