I have to assume that anyone counterfeiting a Sebenza, for example, has a genuine Sebenza in their hands to copy from. Are you really going to point out something from a few internet pictures that they can't already see from holding the REAL one and their COUNTERFEIT example in their own hands and comparing them? I doubt it. It really only serves to keep info from those of us who are new to the brand and have not handled dozens or hundreds of CRKs already, and may not pick up on the tiny details as yet.
I may be new to BF but I am a long-time member and a Moderator at CPF and I have seen many such threads on clones or copies of Surefires, McGizmos, SPYs, you name it. As enthusiasts, we have to help protect each other, and that is by freely sharing information and expertise.
While I don't necessarily like it myself, of course people may choose to share info as they see fit. If it is generally accepted that such info will not be posted openly, and should be shared via PM, I guess that's how it will be. If so, then I would propose a service we had on CPF, which was a "Yellow Pages": a sticky where modders and builders listed things they could do or were willing to give information about to those who had projects they were struggling with. In this case, it could be a sticky where there would simply be a list of members who are CRK experts and are willing to be contacted privately by PM or email to assist with purchases on questionable knives. If they are especially knowledgeable on a specific model or vintage, note that as well. Then instead of these threads, which it appears people don't care for, members could simply look at the list, and quietly contact a member on the list to get the help they need.
Seems like something like that might be helpful to all involved.
I always kick myself after the fact, but if I have any doubt at all, I wait.
