Hello, I am the Guppie. I'm a handy wrench, knife, screwdriver, bottle opener, LED light and I will hang on a belt loop or D-ring. My adjustable wrench jaw opens to 1/2" for light repair and assembly jobs. My high carbon stainless steel blade makes short time of your cutting jobs. My removable bit carrier is also a high intensity LED light and contains two strong magnets to hold it securely to my left side. Also, my carabiner detent will open bottle caps and metal jar lids. How cool is that? Take me home today. No aquarium required.
