When I buy new, I prefer the bling of nice new chrome as much as anyone. With that said, once the tool is out of the wrapper and in the box I really never give another thought to the scars, marks, and other wear marks that appear through use.
As an example, I have heard some guys say that they make sure and put their tools on a tray, or a rag, or carpet, or whatever instead of simply setting their tools on the bare concrete because they do not want to add scratches or other such marks to their tools while using them. A thought like that would never come to me, I do my best to never abuse my tools, but I guess I must be too rough or something to ever do that. Not a bad idea I guess, but it is just not me. The scars I add are just part of the price I pay to complete the job. That is also what makes it easy to be happy with older used and marked tools too though.
I do try to wipe away any major dirt of grease left on any of my tools after the job is done, but I don't get AR and go after all the dirt in the sockets or anything like that though.
