Typically I touch up most knives I get, but I actually like a little "microserration" on most my edges so I generally don't super polish the edge. Most are pretty good, but when you can vastly improve the edge on a new $150 knife with a lansky medium stone that's really pretty sad. I think it says a lot about a manufacturers attention to detail that does not ensure a knife is sharp before sending it out especially at these price points.
The only knife I have been impressed with as of late out of the box was a F01 5.5" fixed blade from Hogue, mirror polished and razor sharp the entire length. It's by far the sharpest best polished edge I've had on a production knife I can remember and the only one I remember when I inspected it that I didn't even consider touching it up, considering it's a thick bladed field knife I was very impressed. Enough that I'm tempted to try one of their folders to see if that attention to detail extends throughout the entire knife. That includes recent benchmades, spydercos, Ritter, ZT, DPX, esee etc. Not that those were bad, but every one of them I felt I could easily improve on out of the box, a couple were bad enough that if I didn't know I could sharpen them I'd never have bought them.
