If you want to make a perfect screwdriver for your screwdriver, you might want to consider the right angle screwdriver. This is a screwdriver with a tiny right angle – you can see it when you hold it up to the light.

This tool is a brilliant idea, but it will only work if you have some kind of tool that you can hold it in exactly the right way. Most screwdrivers don’t allow you to hold them in much more than 1/2 an inch from the head, so your screwdriver will be way off.
