Leather has a "nap" direction. Stroke it one way and it is very smooth, stroke in the other direction and it is rough (or at least not as smooth). So the knuckles have a "nap" direction. You are correct that this direction is not indicated on replacement knuckles. Nor is grain direction indicated on a piece of wood from a lumber yard - yet in many applications grain direction is important. The professional is expected to be able to identify these characteristics and respond accordingly.
