Rings with by-pass shanks are right hand and left hand specific and
are not interchangeable. When creating a ring with a by-pass shank,
the side of the shank closest to the hand should come from the side
of little finger. The ring will then sit straight on the finger.
This is because the skin joining the fingers together is lower
between the little finger and the ring finger than between the ring
finger and the middle finger. If the ring is created with the shank
going the other way, the shank will contact the hand on the middle
finger side first and cause the ring to twist while wearing it. Brad
