What type of sgian Dubh is worn in the Highlands?

[Jacques]

The one on the left I wore as a youngster, the one in the centre during my twenties, and the one on the right I wear now. The latter is made of a cow's rib bone, brass and file steel and sees almost daily use. I think the one on the left was a great-uncle's before me.

The more i look at your photo the more curious i become. Are you able to date the sgian dubh you had as a youngster. Also, do you recall who, where or when your present knife was made?

Thanks much

Jacques
