Have you ever handled one?
Because I get accused of having never owned (or even handled) a Sebenza (which is true, because the design is so obviously inferior it is to me not even worth the trouble of examining one: I think this generally applies to most frame locks), yet people will make assumptions about this Kershaw also having never handled one, and this is assumed to be OK...
The Sebenza is said to have a weak detent, and its lock fails at under fifty pounds, which I am sure even the $25 Kershaw can take. To my eyes, this means the Sebenza is not even a proper knife to begin with... I won't even go into the Titanium/steel lock face wear, when for that price you would at least expect a steel insert for a steel to steel wear, as on the $25 knife... The blade to handle and blade to weight ratios are also both inferior on the $400 knife...
The edge holding on the Sebenza has often proved to be poor, sometimes shockingly so (ie the JRDavis882 testing), so even on that front there is probably is no discernible difference, and the Kershaw may even be a good deal better...
As for the surface finish, what I have seen of the Sebenza in no way looks any better than the Kershaw: Even the primary grind line is less crisp on the $400 knife... Again, get the Kershaw and look at it closely: I've seen enough gigantic close-ups of the Sebenza to know the stonewash finish looks like crap in comparison. All a matter of taste of course, but there you go...

We are all entitled to our opinion, and I am not going to argue with you because you are correct in how you look at a knife in terms of what's important to you.
I will address your points however...
My Sebenza (I have only owned two) does not have anything close to weak detent.
"Lock Failure" does not include putting 50lbs on the spine of a knife. I use the other side.
I do pry with my knife, and stab through material and have never had an issue.
If I was to accidently put load directly on the spine, 50lbs would cover my mistake...anything else is user error.
Blade to handle length ratio?
Blade to handle weight ratio?
These are both personal preferences. I have noticed nothing unusual when using my knife and find the ergonomics as good as it gets for my hands...
I agree that S35Vn at 58 is too soft, and at 60 is a wonderful steel.
I am not sure how exact CRK HT numbers are? Some could be 57 some 61?
My first Sebenza was closer to 58, I was sharpening that thing a ton. My current one holds an edge like 20CV, it's ridiculous.
I miss sharpening....
Lock bar insert? I personally hate them. Just one more part. Perhaps you should look at CRK's, really old ones, and see just how far a well designed frame lock won't travel.
I think the last thing you can accuse CRK of, or worry about is travel on their locks.
As for the finish, grind lines...I have found both of mine to be exceptional. As good if not better than customs I have owned that where two or three times the price.
The blade finish is something "proprietary" to CRK, I guess some people may not like it, things like this don't bother me...it's a different kind of stone wash.
