At the Moot I realised that I find it easier to wear my knife on the left even though I am right handed. I hold the sheath with my left hand and remove/replace the knife with my right, I find this much easier than trying to place a knife (held in my right hand) back into a sheath on my right. On which side do you wear your knife and which is your primary hand?
The same with myself, but interesting or not, the ancient Britons, Iron age in particular were either left handed or drew swords from their right side right handed, which is fine with the earlier anthropomorphic short swords, but it doesn't work so well with the long Gallic swords, but the Romans drew across the body from left to right, something that continued from then on and it was also why we in Britain drive on the wrong side of the road.
I have my old wooden handled Mora marked on the handle as to which side is the edge and so when drawing, I look to see and hold the scabbard accordingly, as there is the potential for the blade to scythe the sheath and my fingers if I am not careful, it is honed that sharp as the scabbard is of the thin boiled leather type and is of the dangler arrangement which can be clipped on and off relatively easily, it also aids when is at an odd angle, the knife hangs according to gravity, no matter at what angle the body is, so up trees and along branches the knife does not fall out.
