Screwdriver Sharpening
The only tools that need maintenance are the screwdrivers. They often lose their sharp/straight edge, making working with them impossible. You will need to sharpen them or bring them to a watchmaker and have them sharpened. You can do it yourself useing a Dremmel and a grinding tool. See the images below. Gently, at the same angle as when new, grind both of the angled sides of the screwdriver. One quick "zip" vertically will straigten the tip of the blade. The screwdrivers are also reversible, so before doing a job, you can make sure the edges on both sides are crisp and ready to go. These diagrams may help...
