returning a sgian dubh to hose?

[Lallans]

As I was taught it, if you can't return the sgian to the sheath without removing it from your hose, you are wearing the whole thing too far down. I believe this was a guideline to discourage what was seen as the improper fashion of wearing the sgian with only the top of the hilt peeping out, suggesting concealment. However that's easy to say unless you're outside at the Games or whatever and walking a lot and your sgian is a sentimental or an expensive one, in which case a deeper carry seems the better part of valour- even if you do have to pull the sheath out to return the knife. And how often is that going to be an issue anyway, and who would notice when it is?
