Carinating vs swedging

Jason or anybody for that matter, I need some help clarifying the difference between a Carinated bracelet and one that has been swedged. These are old style methods that are no longer used but are starting to appear in descriptions of modern made bracelets. I always thought that describing something that was carinated indicated that it was V shaped like a keel, not triangle shaped. I thought this was accomplished by using a chisel on one of the flat surfaces to make the wire curl and leave a deep V on the inside (wrist side) of the piece. However, I am told by someone who claims to know that this method is called swedging and that carination is nothing more than a triangle. This doesn’t make sense to me as a V shape and a triangle are not the same. Can you shed some light?
