This artefact is a barber's chisel for trimming the beards of Wyverns. The hairs of a Wyvern are exceptionally thick and strong, so the human barber would need to use a hammer and chisel to cut each strand. As you can imagine, this was a very skilled and dangerous job. The barber would make a mark on the tool at each Wyvern trimmed. You can see that this was a very experienced tradesman. Artefacts of this quality are extremely rare.
