I think you're saying that "creating home made tooling is a waste of time, and you should just use professional tools"? In which case I agree, for almost all cases. A carpenter trying to build their own saw or chisel would be laughed out of the workshop, and rightly so. However, the mark of a master craftsman is one who can identify when custom tooling are necessary and knows something about how to build them.
