Robert, welcome to the Forums!
I follow Bug's note about your first post

Man, you seem really know what you do want!
This is good and this is also bad for you because it is not easy to put knowledgeable and experienced man into fascination ecstasy. The standard you have pointed mentioning SPYDERCO Military and BENCHMADE AFCK is really high, these knives are hard to beat with any production knife in each price limits.
No one knife is ideal. If you will think hard for years on the project on
Ideal Knife of Your Dream and finally you (or someone for you) will make this knife - even in this case I bet you will consider it is not ideal after some first trials.
On the other hand
The Ideal is something what is better to aim at than to reach. If someone would make really ideal knife - wow! - it would be hard to imagine all after-effects of such event!
Just some loose thoughts...
To don't leave you without any practical advice - take a look onto BENCHMADE
710 Axis Lock if you need ambidextrous knife and can reconcile yourself with tip-up carry or onto their
750 Pinnacle if the ambidexterity is not an issue but you definitely like tip-down mode. This last is quite rust-resistant because it has minimum steel parts in titanium handle and the ATS-34 (145CM in recent run) is available with BT2 coating. If you like it - hurry up, they are going to discontinue it.
