Here is a page about a full tang Sgian Dubh. I really like it. I think done right it could be made to work for formal, but that it definitely is more likely a day knife. I think with a dark wood, ebony, Black Walnut, Culloden Bog Oak, Purple Heart, and Pewter, or Silver bolsters, and a stone embedded on the handle, it could go as high as semi formal. I like the idea of a dark wood, and a horn one.
