Josh,
I assume you're asking about the bag carry method illustrated on the page I referenced. The knife on the strap of the bag doesn't swing around unacceptably under general hiking conditions. If I was going to run downhill, cross a boulder field or a scree slope, glissade, etc., I would probably put the knife inside the bag or a pack.
The shoulder strap method is similar, but any swing could be eliminated by a horizontal belt over the strap if you wish.
Carry in the back of a coat, in a game pocket or in the lining, does not produce uncomfortable swing, but depending on the coat it may be uncomfortable when you sit down. If you want to take the trouble to do some sewing you can position a pocket where it will be least obtrusive. Nevertheless you probably would not want to drive for long distances carrying this way. This method would definately be considered "concealed."
Sash carry, in the ancient Nepalese style illustrated, should work well with a modern belt. A protrusion on the sheath to hook the belt may be necessarry to prevent the sheath from sliding through. A nut and bolt could probably be made to serve, although I'm sure the sheathmakers on the forum could come up with a better looking solution.
