First, there is no fun in buying if you can produce one. Sometimes when repairing stuff in the garage and suddenly realize that you need a tool wich you don't have, it always happens to be Friday 8 o'clock and all hardware stores are closed until Monday. Ebay needs a couple of days to deliver. So the best thing is to produce your own tools. Most of my tools are hand made by myself. I was very poor when I started young and hadn't the luxury of many people to afford new tools. So, thumbs up for this instructable!
