I have what I would call a reasonable amount of tools,owning a home,two cars,lawn mower,lawn tractor,utility trailer,snow blowers and a woodshop full of machines takes a variety.I for instance last spring got a new lawn tractor which was Metric.I visualized the tools I would need to work on it,that was the time to evaluate and upgrade if needed.And good quality,the right tool for the job makes for me,wrenching fun
