Couple things to note about the screen used stuff.
Two of the knives are always in the wrong sheath's except for one scene.
The left handed sheath is usually worn on the right hip, and the right handed sheath is usually worn on the left hip. You can see this when he sharpens the knives, and also in the opening fight scene. However in the final battle they swap and the left handed sheath is on the left hip and right handed sheath is on the right hip.
One of the small sheath's sewn onto the bigger sheath face is only sewn at the top, so it can move freely if you bend your leg. You can see this in the final battle a couple of times where it's flapping around. However the exact same sheath in the monk killing scene is clearly sewn all the way round and rigid to the bigger sheath.
Reason i'm pointing this out..................... it was a proper nightmare at times trying to get references.
Should anyone see something that needs pointing out.................. please point it out and i can change it.
