Does someone has noticed that the knife of RedJohn by its form could correspond to a hunting knife, more precisely a knife to carve the animals, and we learn that Tom McAllister was a hunter (if he tells the truth)..But as usual it doesn't mean anything and we can find this clue a bit too easy..We as viewers have already seen this knife several times, but not the protagonists, or...yes maybe Jane in the S02 finale when he met masked RedJohn. So if RedJohn is aware that Jane has already seen his particular knife, he probably be more prudent and don't tell him he was a hunter to prevent Jane think of a potential link...
