Sgian Dubh Outside the Hose?

[Cygnus]

I had a customer come into the shop with an antique Sgain that had a spring clip on the outside of the sheath. The Clan Crest was mounted on the clip. Exactly like the one shown here.

I was wondering what the clip was for. I had thought that it would clip to the top of the hose but this makes it perfectly clear.

Sadly I did not take a photo.

I really wish you had been able to get a photo - various internet searches haven't shown anything so far.

Like I said, I actually like the way it looks (whether traditional or not) and would like to see the real thing before deciding if I want to pursue having one made or modifying an existing sgian dubh.

Maybe somebody else on here has one or has pictures of something similar...
