Actually I trust the "customer marketing" more than any paid advertisement. In our choice of hobby however, is there any other type of marketing

? It would be ironic of you to criticize how these knives get promoted when it is more or less the ONLY way it gets promoted(i.e. praise of Spyderco's Para2 gets around the same way as the CRK Sebenza). And IIRC, Spyderco forums have their own section for reporting counterfeits. So I think it's safe to say that almost every company has their own fanbase that do the same things.
As for MSRP, I believe all of those are never worth it for the simple fact that they make it that high to encourage sales through dealers.
Honestly, if you just want to buy a knife for cutting things, you can accomplish that with a $10 Made in China PoS.
I think everybody shells out more money than they
need to on
something. Some buy cameras, some like lights, some like cars, some like music, some like clothes(and purses, and shoes), some like jewelry. And we happen to like knives.
I think I can understand where you're coming from. You're not the type of person to spend money on a Rolex or a $20,000 camera because you feel you've overpaid for these items to do its basic function about $19,700 ago. That however does not mean that you overpaid by any means(in the sense that you did not get what you paid for). I say this because said items can hold their value quite well and can easily be sold.
So essentially, it's not like you don't get what you sink money into for a Sebenza(fit and finish), it's just that you expected something
else for your money(something like a mythical super duper steel that will NEVER go dull and can cut through a steel pole).
If you wish to prove your point around here, you'd need to find another knife of similar or superior materials(handle, blade steel) and you'd need to show that it has equal or superior fit and finish to the Sebenza for a lower cost. Anything less however and whatever else you have to say will fall flat on its face.
