The wording on these is slightly different but I don't know if it's lazy writing or if they're actually meant to do different things.
The Battle Harness Armor property reads: “As a free action, you can draw a sheathed weapon or retrieve a stowed item.” Does that mean that you can't stow the items away again as a free action? That you must drop them or spend a minor action to do so?
The Avalanche Hurler U12, Quick Draw Trick reads: “You draw or stow one or two weapons.” Does that mean that you can only draw weapons as a free action but not other items?
The Disembodied Hand reads: “You can retrieve or stow an item as a free action instead of as a minor action.” I'd think that weapons are items but since the Battle Harness Armor specifically mentions both then perhaps this doesn't work with weapons? Is an implement a weapon?
