Made a pair of obsidian daggers as a birthday present for a lovely Mistborn.

The the handles are bone wrapped with koloss leather.  I'd never knapped any sort of glass or flint before, so this was a learning experience!  They aren't as pretty as a more advanced craftsman could create, but the birthday girl really loves them and keeps threatening to stab me, so that's what counts.
