1900-1924 H Boker & Co Solingen Germany Folding Pen Knife

A huge chestnut tree that towered over the small hand tool factory of the Boker family in Remscheid in the 17th century is the name-giver of the Boker Baumwerk. The industrialist family first registered the trademark with the famous tree as a trademark in 1674. It shows a green tree on a silver background on the banks of a blue river. The high-quality Boker tools were extremely successful, and almost 100 years later they were among the leading products in Germany and neighbouring countries.
The family realised that henceforth the tasks had to be distributed among themselves in order to make the best use of the potential. So Hermann Boker emigrated and founded H. Boker & Co. in New York. Their cousin Heinrich Boker merely crossed the Wupper and went to Solingen, where the German cutlery industry was developing with enormous speed at the time. Together with Hermann Heuser, an extremely accomplished cutlery expert, he founded Heinr. Boker & Co. in 1869.
The Bokers in Remscheid and their cousins overseas showed great interest in the high-quality razors, scissors and pocket knives from Heinrich's new company. They had to mark their products for the overseas markets in a simple way, because many customers had problems with the German name Boker, not to mention the widespread illiteracy of the time. Heinrich Boker chose the huge chestnut tree, which was already 200 years old at the time and had already been used by the hand tool factory as its coat of arms, as a memorable trademark.
