The majority of us don't use power tools every day, and chances are you have a box or cabinet somewhere with cords and cables sticking out everywhere. Instructables user KaceyK shows a simple method to wrap cords so they don't stretch out and they stay organised.
The wrapping process is a pretty simple overhand knot (the same method we like for USB cables), but it works a lot better than simply wrapping the cord around the tool. Start by folding the cord in half as many times as it takes to get to about 18-24 inches (45-60cm) and then tie it with an overhand knot. When the knot it tied, loop the cord through the tool's handle and you're done. Hit up Instructables for a full visual walkthrough of the process.
