OK, here is my answer.
Flicking open a Sebenza will not harm the knife any more than flicking open any other similar knife, but what im guessing is that Mr. Reeve is a somewhat stubborn man and according to his personal understanding of a fine folding knife, flicking is not appropriate and thus he refuses to allow it, not because it will hurt the knife so much as he's just a stubborn man and it goes against his principles. It also strikes me this stubbornness is the reason he wont offer a different clip position. It may also be his stubbornness that allows him to produce the highest quality production knife available with knife to knife consistancy that most custom makers can only dream of.
If youre like me and crave ultimate precision and attention to detail, the Sebenza is an excellent value, if you want a knife to cut stuff and dont care a whole lot about workmanship, detail, and extreme precision then i agree, there are cheaper knives that will work just fine. I realize that youre paying a lot for that last little bit of refinement in a Sebenza, to me its worth it, it isnt to others, as always, its a personal choice.
Quick example, im into high-end automatic watches, i enjoy wearing a mechanical marvel on my wrist, a high quality automatic movement is truly a miracle of design and execution and i love them for their complexity and precision, however, i freely admit that my Casio G-Shock will keep better time, and do everything a nice auto watch will and then some, but its still the autos i come back to because again, i love any device thats made with extreme precision and quality materials, even if, as is the case with watches, there is not any advantage in utility. Its quality and precision i crave and that costs money, whether its watches, guns, knives etc.
