Ideal for small tool boxes with just a few tools that can be used very universally and flexibly. The Wera Joker is not cheap, but it is good value, replaces several open-end wrenches and is also suitable for screws in between sizes. I often use it for bicycle repairs on ice.

We firmly believe that our tools make our users' lives easier, safer and "full of joy". We are never satisfied with existing standards. There are many screwdriving tools. But unlike others, we don't believe that tools have been invented to the end. We are constantly looking for new ideas. We think differently. We question. And in doing so, we develop screwdriving tools such as the Zyklop ratchet or the Joker open-end spanner that turn the tried and tested on its head. With over 3,000 different tools to choose from, we are sure to have the right tool for you. 750 Wera Tool Rebels have fun reinventing screwdriving tools every day and working on solutions for you.   We love innovation.
