i have a Boker that looks just like that but the tree stamp is the other way and it isnt numbered....... tried looking through the wiki but i can find yours or mine? guess its just a regular boker w/ barbers notch? do the branches on the tree have something to do w/ the time period of the blade? i like that puma aswell! i cant seem to get a good shave from my boker tho. think the grind is too heavy.
