When I use a quality knife it always as a last resort, having exhausted all other possibilities. I know of no other kind of knives.
What I understand by "quality knife" is something that is actually fairly rare: It has to be large, fixed blade and yet thin edged: No more than 0.020"-0.030", hold up well at 12 degrees per side, and be tested hard at least once, to see if the base/apex is not burned out by power tools (which shows up quickly at this thinness).
This may come as a shock to people, who routinely post perfectly pristine knives and claim to use them heavily, but using knives is essentially the same as destroying them as emergency items... Hollow grinds put on an appearance of durability because the sides of the edge are parallel for some height (I call this "the reserve"), so that they actually don't lose much potential sharpness for quite a while. This makes hollow grinds inherently superior in long-term durability...
Flat ground knives lose potential sharpness the very moment they are used: Because of this, I was bummed out to find out they combine better with round Hollow Handles, because this negative feature makes them much more stable when chopping wood: No sideways rolling...
I will only use quality knives that I don't like for one reason or another, And I tend not to keep knives I don't like... I only ever use the very bottom of my collection: It is a tricky thing, because good knives being rare, it is rare to find a good one I don't like, but still think is good enough to carry or use... I learned some time ago I will only ever use the worst knife I own, so I make sure the worst is still very good, and I routinely throw away worse knives that I know I would be tempted to use.
I test knives hard for functionality, and those that did the best are re-sharpened one last time and absolutely will never be used again, even in an End of the World scenario: End of the World is the next rung down...

Que??
Didn't get much sense out of that.
