I don't have a dog in this fight, but it certainly looks like there's a smoking gun with that set of knives you just showed.
Speaking only for myself, I cannot imagine being a faker and ruining my reputation for the sake of a quick buck. Maybe it's just me, but that's how I feel. I'd rather never sell a knife, but walk away with the satisfaction of knowing that the whole thing was my idea and my work...than turn a quick profit by decieving someone into buying a lie.
Again, just my opinion.
