I would say the two pieces are original, I am sure there is no strict pattern to most Congo knives. It is a good repair but done some time after the original forging. I do not think you payed much for it so maybe you could just keep it untill a better one comes along. What I do not like is what seems an intentional deceit by the seller. Leaving negative feed back is a duel edged sword
, you receiving it when not deserved. If it was a lot of money I would not care about feed back.
