A person needs both. Most Ferrari owners used a daily driver as well. I chose a Boker Cop Tool for my last job, cause it was rough on tools. So, for $30, I had a tool I could use, and abuse. I would never take a $200 knife to that job, a disposable razor knife was more appropriate for scraping silicone caulk off of stucco walls.
In other situations, like camping, I want a reliable tool that holds an edge, and offers comfort, ie. no hot spots, and has great control.
My most expensive knife is about $250, but my other cheaper knives are the "beaters". I find an Ontario Afghan to be a great knife for the price, and I don't mind beating on it, hard if need be, but I wouldn't do that to thinner, sharper, and more expensive knives from Fiddleback, or Bark River.
