We Need More Tools

I had to take my sewing machine apart to change the belt and I was on the hunt for a darn screw driver. It dawned on me right then , that we do not have hardly any tools. How are we going to be more self-sufficient and prepared of we do not have any tools?? What would happen if something needed fixed? How would we cut anything if we had no saw?? I just really think that this needs to be another important thing for me to be on the lookout for. Hope I can find them at thrift stores and yard sales.
