 Well, it's ""fashion"" on purpose because it's unlikely that you'll come across something already perfectly broken and ready for use. I didn't change it to ""shiv"" in the text because it's more or less a ""shard"" being used as a ""shiv"", but it's definitely not a knife as it had been changed to. Also, when Luthor picks it up, he doesn't let anyone know about it, and when he uses it, he uses it in a way that models prisoners (the twist and break off for maximum damage in one hit). I also didn't change it because it's relatively original research, as it's never stated in the movie what it is or how he is using it. I think had he wrapped some tape around the end, it would have been more closer to the definition of ""fashioning"" a device. You could take a sliver of glass and wrap tape around for a handle and that's a shiv. Anyway, I was only trying to say that it wasn't a ""knife"", and definitely wasn't a reference to Darkseid's knife, in the edit summary.  "
