Okay, heres the thing. ive never owned what you would call a quality knife, and i would like some out side opinions on a good manufacturer. Im looking for a pocket knife thats easy to conceal, that i could whip out with the flick of a wrist and defend myself if necessary . also it would be nice if it were "tool worthy."
By tool worthy i mean i need to be able to take this fucker out and use it as an emergency pryer, screwdriver, whatever.
Also, i would like some opinions on sharpening stones. Right now i have a DMT sharpening stone. Im not very good at using those long chef knife sharpeners, so those are out

.
I dont really like those sharpeners thats take 3 swipes are so and your blade is good to go. i like to practice at getting as good of an edge as i can with a normal, rectangular stone.
so...any adivce?
oh, and what i have resembles this...

it was a hand-me-down
