The Hannan has quite an interesting handle. That tree symbol is also on my Boker. I guess it is their company symbol.
Yes, the tree is a symbol of their company. Here are some links to their "about" pages in both English and German. I also hyperlinked the picture they have that shows the use of the tree symbol throughout their company history. http://www.boker.de/us/history.html http://www.boker.de/unternehmensgeschichte.html
