The above weapon is rather ambiguous along with several other weapons similar to it. While in the book it states the damage (d4 I think?) it also refers to unarmed attacks while equipped with it. "your unarmed strikes may deal bludgeoning or piercing damage" I was wondering if you are considered unarmed for this weapon in terms of monk damage, ki strike, etc or is this another weapon like a sword (mechanically).

Basically, could a monk equip this weapon and deal his unarmed damage, ki strike, etc while having it enchanted to be a +5 weapon adding the normal benefits?

Adventurer's Armory Errata Changed the Cestus from an Unarmed Attack to a Light Weapon.

So no, a Monk cannot deal his unarmed damage with this (or any other) weapon. It has also changed in the PRD - Please note that the Brass Knucles are incorrectly listed (still) as an unarmed attack - they have also been erratad to Light Weapons

Hence we have complaints that brass knuckles have been profoundly "nerfed".
