So nice to see people not drooling uncontrollably over a Sebenza. Don't get me wrong, they are nice. At $200 they would be killer, $250 not too bad. Once you hit $300, though, they lack that certain "oomph". I know the tolerances are high, but that doesn't warrant a price tag of double what a production version would cost. My big turn off is the blade steel using something a little more premium would NOT kill them. I'm not saying use S110V, but some Elmax or something else wouldn't be a bad idea.
Put it this way if your options for a car are a standard Corvette, or something identical to a Corvette that is made a little better at twice the cost (with 0 style or performance increases), which would you choose? I would opt for the cheaper one, and if I was going to spend the money anyways get a second Corvette (in this hypothetical I am filthy rich) or a suped up version of the standard.
I will reiterate- the Sebenza is not a bad knife. It is just a bit overpriced.
