I was saddened when I saw a lack of the Scrimshaw ranked skill. I think this would be a fantastic addition toward artisans and people who like to craft things. It is the fine and delicate art of carving bone, typically using fish bones. Sometimes a scrimshaw carver will put inlays of metal into their work and as such I have allowed for similar things with this skill suggestion and incorporated a requirement to match it.
