I don't disagree with any of your points really.
And yes, it is really difficult to imagine a scenario where one might be stuck with only one knife. If that were ever to be the case, something that simply cuts is going to be your absolute best friend.
The gist of my prior point is this: If a cutler makes a knife that is meant to be big, robust, and stout, then I would expect such a knife to be big, robust, and stout - a knife that is suitable for whatever chorin' that comes up. The 97 is big (for a slipjoint), robust (in materials and appearance), and stout (again in materials and appearance). The weak action ruins it for me - if it didn't have a half stop, I would think it was an Opinel without its collar. I guess, in short, the size and appearance of such a knife is wasted on this one where the action is just a hair away from needing to be push closed.
All that to say, I have no doubts that it makes for a mighty fine dinner knife.
To your comments about the 23LL - I, too, had some difficulties with using the thumb of my main hand to depress the lockbar - it felt very precarious. I mentioned this in the 23 thread and a technique was mentioned that I adopted pretty quickly. I use two hands now - use my left to depress the lockbar and use my right to ease the blade into the half stop position and then use my right thumb or leg to snap it closed the rest of the way. Works like a charm - 'tis a different beast than modern liner locks, for sure.
