MERK, even after all of these years, you never cease to amaze me
I think you'd be happiest looking catalog pictures of master sets then
I disagree with you that professional tools are born and not made professional through use. To me professional tools aren't judged solely my the name that is stamped into them but, how they stand the test of time with consistent daily hard use over years of service.
The second aspect of professional tools you omit is the skill of the person using the tool. A novice wielding a snap on wrench will not achieve the same results as a seasoned tech using an OEM brand wrench. Tools in themselves do not magically make one professional, it's the skill of the person using them that matters. I can think of no better example than that superautobacs guy that illustrates really complex use of japanese made tools being used on european cars.
I know several techs that have all one brand of tools in a matching box but, i'm not one of them because, i don't think one brand makes the best of everything but, that's just me.
You are truly blessed though to have the skill of instantly knowing if a tool is professional simply by looking at the brand and part number though. I have to put a tool through its paces for awhile before i can do that. Of course Proto has the word professional stamped into some of their tools so, that's makes it easier.
