I really like the set of drivers I got from Wiha tools, I think it is the Power Drive line. They come in every size you could need for knives, and I have yet to strip a head.
BTW, torx are used in other places too. Automotive work, computers and other electronics are just somethings that come to mind. Basically it is just a simple way to keep the average idiot out as he will just cause more problems. If yoy are smart enough to find the right size and type of driver then you can probably take the thing apart and get it back together.
