how could someone's belly be tortured?

it can range from anything from pulling the flesh off with pliers to electrocution to non-lethal stabbing (the goal is to make it last for a while)

there's also disembowelment but it's not really creative? i mean just cutting them open and pulling everything out has gotten kinda common so i'm looking for some creativity there like for example hooks or rubbing the intestines with salt or something or maybe making a small cut on the belly and shoving your entire hand inside to fuck about the organs lol

they can die at the end but it has to last atleast a few hours. you can suggest methods for inside or outside the abdomen or both cuz i'm at the end of my imagination

(pls don't say the rat and bucket method that's the oldest play in the book and everyone already knows about it)
