It is entirely possible, although I have never seen any documented evidence. In one of my sourcebooks, BONZER is mentioned as being German made circa 1950-1980. Some have suggested that it may be an attempt to ride the coattails of the BONSA brand, but that is unlikely since BONSA was not a well known brand either.

I am beginning to wonder if BONZER may have been made for the Australian market. BONZER is slang, meaning "excellent, awesome, great, fantastic" or something along those lines. Wouldn't surprise me at all if Boker, Klaas, Henckel, or Olbertz made them for export to Australia...

Got any pics to share of your knife?

Great stuff Roger!

That is only the second time I've seen reference to the Tree trademark being registered in 1867. Most resources claim 1869, when the new H. Boker knifeworks were built in Solingen. However, it is documented that H. Boker & Co. in NY was using "the representation of a leafless tree" as early as 1867!

Here's a few other trademarks used by Boker:


Wyeth's Warranted Cutlery (1860-?)


Radium was trademarked by Boker in 1904.


Baumwerk is German for tree works.
