Wow. Just found this thread. There is nothing wrong with having a Kennedy toolbox, but I have a big problem with people who would judge a person's ability based on what kind of toolbox he owns. A person that would judge based on trivial matters such as this is in my opinion a narrow minded idiot. Plain and simple. An employer that would make this kind of judgement is even worse as this is sending a signal that toolbox appearance is more important than work results. Quite frankly, I wouldn't want to work for such a person, or hire his business if this is the kind of thing he places importance on.
I happen to have a Craftsman roller cabinet that I value more than any other toolchest could ever match. It was given to me by my grandfather who passed away just a few years after I received it. I used that cabinet at every machinist job I had. So I guess it was unprofessional or uncaring of my profession to use a toolbox I value more than any toolbox ever made simply because it was red and not crinkled green.
Bottom line is that a person's ability, or professionalism can't be judged by looking at his toolbox.
