If ever there was a tool that was a niche toolmaker for professionals, Gedore would probably be that toolmaker. Gedore started making tools in 1919 out of a small forge in Dowidat, Germany, but like many other toolmakers, they have grown immensely since then. While Gedore does make extremely durable versions of the most common tools like screwdrivers, wrenches and hammers, Gedore also makes highly specialized tools like torque tools specially designed for heat exchangers and many more unique tasks. If you’re looking for reliable tools to do ultra-specialized jobs, Gedore may be right for you.
