So I'm making a pair of a Mistborn's obsidian knives as a present, but I'm a bit stuck on the design phase. Traditionally, an obsidian or flint knife would be attached to a haft with pine pitch and tied with leather or sinew, but I am pretty sure that they didn't have pine trees in the Final Empire.
What sort of material do y'all think the haft would be made of (wood? Bone? Antler?), and how would it be attached? I can always use modern epoxy as the adhesive and wrap it with something cool looking, as well. Or maybe it is a solid piece of glass, with a leather or cloth wrapped handle. From what I recall, the hafting for a glass knife was never really discussed in the series, but it's definitely possible I'm just forgetting.
