Rare collector item. The handle is marked with the mighty tree used as the companies symbol. I believe this to be around 1910 or so. The Beginnings In the 17th century, a mighty chestnut tree overshadowed the small tool factory of the Boker family in Remscheid. This tree would later become the namesake and enduring symbol of the Boker Tree Brand. The family first registered the crest in 1674: a green tree on a silver background by the bank of a blue river. Boker's high-quality tools quickly gained success, and within a century they were among the leading products in Germany and neighboring countries. In the early 1960s, Boker USA was sold, eventually coming under the ownership of Wiss & Sons, a well-known scissor manufacturer. Wiss continued producing Boker knives and selling them alongside Solingen-made products, though Boker scissors disappeared from the U.S. market to avoid competing with Wiss's own line. The leather case is showing age but still serviceable. 12-22a
