I generally prefer full flat grind or scandi grind knives. I generally prefer carbon steel knifes to stainless. I generally prefer a fixed knife to be 4.25-4.75" and a folding knife to be 3.25" or less. BUT I love the Buck 110. One of my buddies has one his grandfather gave him thats 60+ years old and still locks up solid and is as sharp as anything. I myself have two 110s. One traditional with the black leather sheath, and one of the new "lightweight" ones with the zytel handle and nylon sheath at half the weight. Love them both.
For field sharpening I've lately fallen in love with the WorkSharp Field model sharpener. Everything you need and nothing you don't.
I am of same view as you , Jeffrey . Flat grind blades are the easiest to sharpen in the field . A carbon steel knife is extremely easy to sharpen and can take an extremely keen edge quite quickly . I used to own a Sheffield Navy clasp knife during my youth and it used to have a carbon steel blade . You could get it razor sharp , just by sharpening it on a common Ganges River rock and then stropping it a few times on a coarse piece of leather . In fact , I often used that knife as a makeshift razor for shaving in the shikar camp , if I did not possess a Gillette Safety Razor with me , at the time .
In India , virtually all of our locally made knives were made from the spring steel taken from the leaf springs of disused motorized vehicles back in those days . Vehicular leaf springs are actually made from 5160 carbon steel ( which makes for a very fine steel , if you have a fair degree of forging skills . ) . The blades were extremely strong and could take a very fine edge rather quickly . They were extremely easy to sharpen on the common rocks found near streams in India . Their only drawback was that they possessed no degree of corrosion resistance whatsoever and you constantly had to keep them oiled .
However , a Buck Model 110 lock back folding knife is a thing of unrivalled beauty . My professional shikaree partner , the late Tobin Stakkatz used to own 1 early model Buck Model 110 lock back folding knife , which utilized a 440C stainless steel blade . It did not take as fine an edge , as a carbon steel blade ( Since 440C is a coarse grain steel , with large carbides ) . It was also extremely difficult to sharpen . However , it resisted corrosion extremely well and held a working edge far longer than a carbon steel knife .
My Buck Model 110 lock back folding knife came with a black leather pouch , as well.
