Whatever the condition of the knife, you are posting in the negative after 1 1/2 years. This is after you admitted you posted positives for the transaction originally.
Doesn't seem like you have given the Seller time to respond to your now changed-mind for a refund, yet you make this post attacking him.
You also admit that you have had a "falling out" with Mr. Vincent, so your motives are suspect.
If I were Dale Vincent, I'd tell you to go pound sand at this point.
