So I decided that I would spend my holidays teaching myself to make Sgians dubh. I've ordered three blades and I'm about to order wood for the handles. I started to plan the sheath and realized from the different threads here that most sheaths are wood. I was planning leather but now I'm not sure.

I'm better with steel and leather than I am with wood but the wood sheaths do look nice.

I've also realized that my collection is all solid sheaths, mostly some kind of plastic. One is solid with a nice leather covering. (I have a collection because of an ebay mistake: thought the guy was a collector who knew the terms he used, wrong but I did get a Wilkinson Sword Sgian Dubh, the rest were not really worth anything.)

So give me some discussion on leather versus wood sheath, please.
