as far as shiny as new vs nice patina... i try to keep my blades looking like they're new in box, until that first major scratch, ding, or whatever. Then all bets are off and i just keep it sharp and oiled up. Whatever patina it gets, stays. The only other thing is if I'm collecting a knife for show...they only see phone book paper or special occasion carry. I've got a microtech that I've only carried twice, but it's so cool (to me) that i can't bring myself to EDC it. You should see my bark river knives after water stone sharpening.... bottom half is mirror polished, top is factory 600 grit satin. Looks like crap where the two scratch pattetns meet, but man are they sharp!
