Rather nitpicky

, but I´d say the straight spined Stretch tip is no thinner indeed than an Endura at the tip when one looks at the spines of the blade.
The Endura tip (and even more so the tip of the regular Stretch) should be a bit stronger though due to the drop of the spine towards the tip, which makes it less "pointy" when looked at the tip at the flat (and not the spine) of the blade (I think it even was Sals intention to give Endura 4 and Delica 4 that kind of "spine drop" to make the tip a bit more robust in that models?)
Again, rather theoretical, and I´d guess not relevant for sd at all if one deals with an SS Stretch or Endura tip...
I know nothing at all about sd with knives, but just instinctively I´d probably take the SS Stretch over the Endura if I had to choose (and then still avoid any knife fight...

)
Yes, you’re no doubt right on the relative tip robustness, Wartstein.
And even more right when you alluded at the end of your post to the best defence in a knife fight is not being there in the first place, if at all possible.
Any hunter can attest to the fact that puncturing a mammal with a hole, or multiple holes is no guarantee of an immediate stop - even when vital organs are successfully targeted.
I think this explains why we often hear of criminal stabbing cases where dozens of stab wounds were inflicted. The perpetrator no doubt expected one or two penetrations to stop the victim cold, when that’s mostly not going to happen.
I once put a .308 cal 180 grain Nosler Partition softnose projectile through the heart and both lungs of a large Sambar stag from about 25 metres away, and the stag still ran a couple of hundred metres before dropping.
So I guess this is why experts like Janich focus on slashing strikes that will remove the ability of an assailant to operate the motor functions that they need to continue the assault.
I read a book once by James Ayres, an ex Special Forces Green Beret on ‘tactical folders’. He cited a bunch of cases where a robust tactical folder aided someone in an emergency situation.
One example was a woman working in a shipping container near the Twin Towers on 9/11. The shockwave of the buildings collapsing overturned the shipping container, trapping her inside. A passing fireman heard her cries for help hours later, and used his folding knife and a chunk of concrete to baton into the Cor-ten steel wall of the container, and prise open a gap that allowed her to be rescued.
I doubt the folder was in a very serviceable state afterwards, but it successfully did the job that was required of it.
There were quite a few other examples like this.
After reading these cases, however unlikely they may be, I wondered about the capacity of my usual EDC cutting tools to handle a similar situation.
I realised that even
if the tip broke I would still have a hand tool with a hardened steel blade which would probably do whatever digging or cutting or batoning task that was required of it, to get me or someone else to safety.
At the end of the book, Ayres had a list of some specific folders and fixed blades he recommended. High on the list was the Spyderco Military with its ‘splinter picker’ tip!
As The Deacon said, if a knife saves your life, it’s done its job and paid for itself many times over - whatever condition it ends up in.
