extract gems works on non metal equipment

[Lailoken]

Specifically Old Forest and Trollshaw artifacts. I assume this is just because they are classified as being a greatmaul and a shield respectively, which normally must be metal, so this might not be easy/worth it to fix. (are spoilers allowed in bugs?)

Also, on the flip side, extract doesn't work on sling ammo (which bums me out when I find rare stuff). I realize this is probably intentional.

Also rough leather gloves can be extracted from. Actually lost the willow shield to a keystutter due to this issue.
