Amazing set there Kronckew! The upper one looks like a Scottish shashka!!
OK OK I know, a guy could get kilt for cracks like that!! Just kidding.
Usually I dont get that goofy unless I've had a respectable bit of Drambuie,as in the incident several years ago that led to the unfortunate tulwar waving incident. This event took out the ceiling fan in my den!
Seriously though, I agree with David on the size of the sgian dubh, as most of these were 3-4 " , but later examples, who knows. The antler hilted knife really is attractive, and unusual. It was quite common to utilize broken basket hilt blades to fashion many of these, and these items together comprise the 'gralloch' set for hunting use in butchering and skinning.
Its great to see Scottish weapons posted, they dont come up too often here, although they indeed are within the ethnographic scope.
I always thought the spelling on these was interesting, Dubh = black or dark.
When working on my family geneology I discovered that the correct Gaelic spelling of my name was MacDhubghaill. I decided to leave it like it is obviously....people have enough trouble pronouncing it as it is!!
All best regards,
