MauiRob:
You bring up a very good point,i.e., 'concealibility ',carrying the khuk just behind the right hip does keep it from view somewhat,and in some cases this might be a good thing.I think the Gorkhas went to this carry mainly because the bayonet was on the left side,plus the musket or rifle was carried in the left hand,leaving the right for the khukuri.For me strong side carry is a lot faster,and my sirupati is perfectly fitted to the sheath,but since I am somewhat ambidextrous I find crossdraw carry useful.The way the sheath is designed has alot to do with it.Khukuri sheaths seem to work either way,but my issue golok sheath being high ride works much better as a crossdraw. The Cold Steel ATC sheath is pretty much a strong side deal.Then you have to factor in what else you're carrying,re the Colt Commander above.
Still, I expect my sirupati will let me know....
