It's obvious he knows the answer to that question or he wouldn't have been so dishonest about it.
I think you might actually be Shao.fu.tzer's girlfriend and not Shao himself; the writing style seems a little different. Who knows, maybe there are two of you, and who knows, maybe both deal in knives, and who knows, maybe the two of you have some idea that some deals are made by one of you and some by the other, and it's all arranged so in your minds only one of you is a knife dealer and the other is merely a collector and entitled to sell knives on Bladeforums without paying for a Dealer Membership. You might be able to convince yourselves of that, but it's obvious you know you're not going to be able to convince us of that or you wouldn't have been so dishonest about it in the first place.
