This new patented tool has three main functions. The chain riveter is the main and obvious function, the head tilts for easy operation. The riveting needle is operated by a number 3 Allen screw hidden inside. The other side of the needle is used as an application needle for the wicks. Inside the body you'll find a box to store this part, spare wicks, valve core and spare blades for the knife. The latter is the last main tool of this tool. Strength, light weight, slim profile and precision workmanship as you have come to expect from wolf tooth. Thanks to the magnets and pins, this wrench can be connected to other tools in the 8-Bit range to increase your repair capacity to the maximum you are able to do "in the field" and get you back home safely.
