Launce Barber and Tom Stokes designed the patented* Li'l Guppie™ as part of our innovative I.D. Works™ line of tools. It's a smaller and lighter version of our popular Guppie™. The adjustable wrench jaw opens to 10 mm so you can use it for all kinds of light repair and assembly jobs. It has a small high-carbon stainless steel blade with a Razor-Sharp edge. You can open and close it with one hand using the blade slot. At the Li'l Guppie's tail is a simple blade screwdriver tip that will handle many smaller-size screws in a pinch. The base of the jaw guide has a Phillips screwdriver which will fit smaller Phillips-head screws.
