Went on a crazy ride finding a definitive answer. Just counting the metal parts, zero calories... But Its possible the leather wrap on the handle could add up to 400
Yeah, I mean, considering that those really look more like dirks or something, if it was real swords with leather-covered handles, my instinct is that #1: 400 calories would be more than one sword and #2: you would be dead before you could expend those calories. Did your research confirm that? I may need to take that research ride too.
Well, I mean, that was kind of my point, I guess. Steel is clearly not digestible, but as the other commenter indicated, the leather on the hilts would be... sorta. And if we are talking logic here, is that a giant's stomach, or are those tiny swords? Aren't there other names for tiny swords? Like, dagger?
The more I look at this image, the more I'm just shaking my damn head.
You have to make sure you get the whole-grain existential horror: that refined horror stuff they are selling to kids these days is just empty calories.
