Tsukomogami are just "Gods" that posses an everyday object after they have been used by the proprietary frequently for a long time.
They can be either good or bad depending on how they were threated. If you don't want that object anymore it's recommended to burn the item to show respect to the object itself otherwise if just dumped it may hold a grudge against the proprietary.
Tsukumogami can't posses stuff like electronic devices for various reasons.
Banette could be recognized as a tsukumogami with a grudge.
