There's a lot of good knifes out there. What I am looking for when I reach in my pocket is a tool. First and foremost something strong that can be used to pry stab poke and of course cut.
The other issue I have a with a pocketknife is How it fits in your pocket. I have a few and when I reach my hand into my pocket they are either too bulky or two jagged and rub against my hand in a very uncomfortable way.
And my last issue is priced. More than likely I'm going to be jamming it into a land rover engine bay very soon so buying an extremely nice unit does not make any sense. Or even worse leaving it in the engine bay so the customer can drive around with it for 3 to 5000 miles until I see them again for the next service.
This is the best compromise between quality value and reliability that I've come up with.
