Random rantlet: Who started the whole 'it's a poor craftsperson that blames their tools' thing? No one who has ever made something by hand, I bet. I cringe every time I hear it used. Who is willing to pay the most for good tools, and who is most obsessed with taking good care of them? The best craftspeople, of course. Good tools matter. There is a lot that you simply can't do without high quality, well-maintained tools.
Depends on how you look at it
They can't afford good tools, so when said tools break or fail in the process of creating something, of course they're going to blame them! &;)
Or you could look at it another way. A mark of a bad craftsperson is sloppiness. Thus, they neglect taking proper care of their tools. The tools break, and they blame the tools instead of themselves.
Even if the tools were actually flawed or at fault, shouldn't a good craftsperson detect that and not buy them in the first place?
