While there are many brands of high quality German tools, few are as recognized as Stahlwille. Stahlwille Tools is well known not just for automotive tools, but they’re a brand widely used by the aerospace industry. One of Stahlwille’s contributions to aerospace was the “Tool Control” System which uses bright colors in the storage case that show only when a tool is missing. Stahlwille has also led innovation in aerospace applications by creating tools like the Anti Slip Drive, the Spline Drive the Quick Release and many more. The quality of Stahlwille Tools is among the best, anything less would be disastrous for those in aerospace.
