Böker (German pronunciation: [ˈbøːkɐ]) was one of the first companies to offer ceramic knives as a featured product line.
[1] Böker traces its origin to the 17th century as a tool maker in Germany graduating to swords and blades by the 1800s.
By the 1860s the company had fractured with a branch of the family emigrating to North America and setting up plants in Canada, Mexico and The United States.
The German and North American factories produced similar knives and used the "Tree Brand" trademark.
[3] The production is mainly of knives for leisure, hunting and collection, as well as those for sports and professional use for military and police bodies.
