Could be a sgian dubh

[TheSp8]

I sure can't speak for anyone else, but a knife that can't be used is an ornament, and would never be carried by me.

Yeah, what the Marine said. To me, even an ornamental knife has to be functional. It should be able to clean under my nails, cut a piece of string, or process large game with equal ease. That being said, all commercially made sgian dubh I've seen have been duller than a hammer. We looked at many many in Scotland and all were dull with a few even having questionable points. Bummer.

YMOS,
