Founded in 1919, Adler continues to build on four generations of axe-making know-how in its Waghäusel, Germany factory. What started as a small, southern German blacksmith's shop has become one of the world's authorities on forged goods. The quality's still as great as it's always been, but they've completely overhauled their manufacturing processes over the last few years to make operations as sustainable and eco-friendly as possible.
