koj, etc. list as a noun (~もの), but i agree that it is better glossed as an adjective.  i think handheld is a different sense.  eij lists it with this meaning only as adj-f (similarly to the 手持ちカメラ example above)

I don't think its any sort of *item* (goods, holdings etc.)
Rather, I think it's a *property* of goods or items.
I think "goods on hand" would be something like 手持ち在庫 rather than 手持ち:
手持ち在庫 【てもちざいこ】 stock on hand; WI1

OK.

That's what I would have thought, and that may be "correct usage," but in practice it seems that there might be an overall tendency to use 痛み even for the "damage" sense. For example, I get the following figures:
Google n-gram counts
毛先の痛み 1198
毛先の傷み 1008
(about 20% higher usage for 痛, even though it's the "damage" sense)
With Google Verbatim, the 毛先の痛み figure is 34% higher than it is for 毛先の傷み.
But I don't disagree with the suggested change.

gg5, meikyo

this is probably why

Most of the refs merge them. The odd thing is that it seems I had them merged and at some stage separated them. Can't remember why.
