All true, but also kind of funny that in the olden days of lockless slipjoints made out of 1095 and the like they tended to be very thin and great cutters. Somehow with the invention of locks on folders people decided these are fixed blades or pry bars or metal cutting tools or screwdrivers. Somehow the culture of using knives for cutting morphed into using knives for everything else making them bad cutters in the process.
It's because most people buying modern folders, especially expensive ones, either don't know any better and/or just don't actually use them.
The evolution of actual pocket knife use and the appreciation of proper geometry is expressed in people like Shawn Houston. He realized that the answer lie in the steels and treatment that allowed thin grinds but retained high performance.
I'm especially fond of the dudes that will spend hours debating the nuances of lock design and strength to have their $400 knife spend eternity at best in a pocket but often in it's box. These guys also tend to really want "flickability" and a fidget factor with their super tough lock.
That said, spend your money as you wish and there is something to be said for this trend pushing designs.
