Not sure how valid that one is either.
I added the emphasis.

Short knives carried in various places on the body were usual possessions of men from time immemorial. In Northern Europe throughout the Middle Ages, one always brought one's own cutlery (fork's were not used as eating tools then) when coming to dinner, as the host probably did not have enough for all of the guests.

Was the Sgian Dubh one of these? It could be a descendant.

That it was a skinning/utility knife carried by the Ghilles on a hunt, and picked up by those who hired them as an affectation, has to my "nose" the "smell of truth"

The romanticised one above, is probably much less likely.
