The Sebenza is unsurpassed at its price point for only one thing, as far as I can tell: granting you membership to the smug douchenozzle Sebenza fan club on the Internet.
It's a fine knife, but I've yet to once have anyone explain a single advantage it has in any concrete terms beyond that it is finished to higher tolerances than any other production knife.
Sebenza fans will admit the knife isn't the nicest looking knife, or the best cutting knife, or the strongest knife, of the most fun knife, but will assure you that it is still without a doubt the best knife. If you buy one and find it unimpressive, as I did, you'll find a new wave of unjustified snobbery washing up on your shores. I've been variously told a wide variety of versions of these put downs and humblebrags when discussing my impression of the Sebenza I purchased:
It takes a level of maturity and wisdom to truly understand the magic of the Sebenza
It may not be the best at anything, but when you get to know knives you'll understand that it is still the best knife
If you bought a Sebenza and didn't like it, it's your failing, not the knife's--something is wrong with you
Some people just can't appreciate the finer things
So yeah, it's unsurpassed . . . unsurpassed at giving you immediate access to the self-impressed Sebenza douchenozzle club. Every membership comes with a bonus dose of purchase justification manufactured to 0.0001" tolerances along with a bonus guide for how to explain how all other knives are inferior (e.g. tolerances--make sure to brag about a difference in tolerances so small that a human literally cannot perceive them in comparison, remember to include that CR invented pretty much everything, including the general use of sharp objects, also make sure to mention the manufacturing award-- but conveniently forget that someone else usually wins knife of the year and whatnot).
Bam. I actually didn't write that ^. It was a comment I just found funny in one of the reviews on the Sebenza, so I wanted to share that joy. All hail the Mighty Sebenza. Buy the Sebenza. Join us.
