Every now and then someone comes up with an ingenious and useful tool. The Palm Pal wrench is a small, solid wrench with 14 sizes. It can be used just about any time you would need to use an ordinary wrench. The cool thing about this tool is it's size. It replaces a whole set of wrenches. This tool is ideal for cyclists, campers, survival kits etc. I keep one at the office and in my car. It comes in handy all the time and is built like a tank.
