Boker began as a hardware manufacturer in Solingen, Germany in the 1600’s.  A large chestnut tree grew over the top of the factory and idea for the Tree Brand logo and symbol was born.  In terms of cutlery, Robert and Hermann Boker began making sabers in 1829 and soon were making over 2000 a week.  Pocket knives, razors and scissors were produced in large numbers after the founding of Heinrich Boker & Co. in 1869.  Soon after, the tree logo was selected as a simple and unique way for customers to recognize the brand. In the 1860’s Boker expanded into Mexico and United States (NY).  By 1900, H. Boker & Co NY was making pocket knives as well when it merged with Valley Forge Cutlery in Newark, NJ.  Even though the Boker factory in Solingen was completely destroyed during WWII, the factory was rebuilt and eventually resumed making high quality pocket knives once again!  Here are a list of tang stamps to help date vintage Boker knives.  Check out Carl Schlieper Eye Brand knives and Puma knives as well.  I appreciate any traffic from these links as I earn a commission at no extra cost to you.
