Looking for references to the integrity and wholeness of building your own tools

I am interested in memoirs and research around the craftsman's needs and desires of making his own tools for his work. For example, I once worked for a instrument maker and he made many of this own tools for use in dulcimer and guitar construction. Most of these where jigs but others where more complex like his steamer for bending wood. I have been torn over the years between using someone else's tools for software construction and information management and building my own. I would like to understand how others have come to a settlement on this matter. Perhaps there is no settlement. Perhaps this tension is part of being a craftsman.
