Revisiting this (now that I'm blinging out a different character)...
Is there a chance that we could add the criterion of "UCS weapons" into the 'Weapon Type' section?
https://gswiki.play.net/Unarmed_combat_system#Weapons_Compatible_with_Unarmed_Combat These are a distinct sub-set from "Brawling weapons in general" (which is already there), since these are the ones that, from their descriptions, are actually designed to be worn. (Never mind how GemStone inventory & combat mechanics needs them to work, "held in hand".)
They would still appear for Brawling, but if Brawling were UN-checked they could be selected on their own, and not see all of the katars and blackjacks and whatnot mixed in with them.
