I think you're right. First two gens had the least negative angle, then the 3, and finally the current gen has the most.

That gives a good look at 3 vs 4.

I'm still a bit amazed at how my 100 pound daughter loves her Endura and how odd it felt in my hands. She though, didn't grow up with mostly straight knives or knives that had mildly negative angles. I imagine the longer length makes that angle way more noticeable or obvious than on a shorter bladed knife.
This is such a weird phenomenon. My wife has zero issues using a chefs knife but if I hand her a folder bigger than her dragonflies, it's "too big". I'm talking a native 5 lightweight here, not a police or anything.Evil D wrote: ↑Mon May 31, 2021 2:32 amGrizzly wrote: ↑Mon May 31, 2021 12:38 amThanks everyone for sharing.

I probably grew up with the same knives as you. I remember having a couple Cass slip joints and so many Buck 110's they may as well have come in cereal boxes. The blade angle thing never really occurred to me until after a few years of using Spyderco knives, and I think it was the Military that first opened my eyes to it and the more I used it the more I appreciated it.
Size is always an interesting topic. If you hand a person a 10 inch chef's knife and ask them to cut up a tomato they won't think twice about the size of the knife but if you pull out a 4 inch blade folder that same person acts like you just pulled a machete out of your pocket.
Yes, they would be neutral angle. I had to search the Emerson A-100 to see. When I did, I noticed the flipper disc on top of the blade that is screwed into the spine of the blade. Years ago I had a Katz folder made that way. One day i locked myself out of my Astro van and the only thing I had to pry open that side window was my knife. So i pried with it enough that I got the coat hanger in there to work the latch, but at that moment the blade snapped. I knew it might and used it anyway. But where it snapped was right along the line where the spine had been drilled for the screw that attached the flipper disc to open the blade. I'm no engineer, but I would imagine that is somewhat like scoring glass so as to break it along the score line. I'd bet that if that blade had not been drilled that way, it might not have snapped that day. That is one feature I always shy away from whenever I see it now. I still have that snapped blade in my tool box. I really missed that little folder since it had a bit of recurve to the blade and i always did enjoy using it. But, I would not replace it because of what I believed to be a weakness in that design.
Heres an example of a straight / neutral blade - the Protech Godson - which is a modern version of the classic Italian Stiletto.

Behind it is the Spyderco Ayoob - one of the most extreme Negative Blade Angle (NBA) models Spyderco has ever produced.
If we imagine pull cutting (say, slicing open a box or slicing through carpet) you can see how much more you need to bend the wrist to put a straight knife's edge into the material.

Woah, it’s handy having a neat and simple list like this to keep in mind!Ed Schempp wrote: ↑Sat Jun 19, 2021 8:18 pmI’ll try again I got timed out on this post on my first go around, here’s my list!
1) better blade purchase
2) less wrist action more grip durability!
3) large muscle groups of forearm and shoulder do the work!
4) in reverse grip edge out blade is 90 degrees to forearm for better puncturing!
5) in reverse grip in a punch slash motion blade is best position for purchase!
6) in a thrust motion you have mass of arm behind the line of force not beside where it can slip.
7) the”C” allows for more torsion on the piece verses trying to twist a straight piece.
These are most of the reasons that I incorporate this negative blade angle into my designs…Ed Schempp
