Since when is personal safety considered ridiculous? The very notion of blowing off the safety concern while working on any project would be ridiculous. There are just as many young readers of this site as their are old tinkering sorts. The cost of that #4 Torx driver is much less than the cost of an eye or a trip to the hospital for stitches. My theory is that if you need a tool (especially one as inexpensive as a Torx driver set) for one project, you are likely going to need that same tool for another project in the near future. If not, consider borrowing one from a friend or relative. It's just common sense. Safety should always be in the forefront of any project. You shouldn't assume anything about the readers of this site. If most were honest, I'd bet the stories of getting injured while not using the right tool for the right job would never end.
