The Sebenza is so simple and so perfect. People always say that you can find other knives by other makers that compare overall for much less money but that's just false, IMO. There is not one Benchmade or Spyderco on the market that is made to the same tolerances or level of perfection that CRK's are made to. Granted, I love Spyderco and appreciate Benchmade and I'm sure any one of their knives, even down to the Chinese models, would last any normal person a lifetime.
I'm talking about refinement and nuance that can only be experienced by holding, using or taking down and cleaning a CRK. If you hold a Sebenza in your hand and really look at how perfectly it's made and how tightly everything fits and how simple and robust the construction is and you still can't understand why a Sebenza is placed on this pedestal and considered a cut above, you simply shouldn't own one.
As much as I love the Spyderco Para 2, for instance, not only would it void the warranty if I was to disassemble one, who knows if it would go back together the way it came apart. Knives like the Para 2 and most other production designs can require a certain amount of adjusting to get the knife re-assembled and centered the way it came new. While I agree that this doesn't make the Para 2 a bad design, I think the fact that CRK gives an Allen wrench with every Sebenza speaks to how simple and well built the Sebenza really is. I'll take simplicity and perfection over anything and that's what the Sebenza provides. I've taken both of my Sebenza's apart a couple of times for cleaning or lanyard tinkering and both have gone back together flawlessly with everything tight and centered.
You can surely find other knives that cut just as good as a Sebenza or maybe look better, in your opinion, and at a fraction of the cost. Personally, if that was all I cared about, I wouldn't be a knife enthusiast. Who cares about having the bare minimum of what you need when you can indulge in what you want?
Why buy a Porsche when you can spend the same money on a Honda Civic and make it a 10-second race car? I suppose that's for each individual to decide for themselves.
The Sebenza is greater than the sum of it's parts and I'd guess that when you ask 98% of people who own CRK's, they'll agree that you get what you pay for.
