Right you are Will, the B does look different! Might just be the way it was struck or wear from the pivot? Off topic but I see from this post you are from Finland! I have a couple glorious Puukot (Google tells me that is the plural noun?) from your homeland. Great knives.
Jack, I'm making an assumption here but yours looks older than mine? Yours has an older looking serif font and mine has no markings on the reverse of the tang. What say you?
Also, my silly ocd wouldn't allow me tolerate the similar wear mine had to yours. Here it is as found marked up ready for the file...
Like yourself I won't be carrying this too much. Despite the fact its obviously a "gentleman's knife" rather than a quickly deployed weapon I'm sure the fuzz would take a dim view. Shame as I really like it, and its demonically sharp

Dig the fruit knife!
As an aside what's your thoughts on the use of English on German knives? Obviously they were for export but somehow I think I'd prefer one in German for the home market, would seem more genuine to me??
There's a few kicking about online but little for sale. I kinda chanced upon it as the guy who had it was apprehensive about advertising it due to rules n regs.
Best post some Germanic sharp stuff and stop waffling
Tinchy little whittler with lovely grinds on that main. The tortoise shell was nibbled by something bug like in the past but I do like it. This thread inspired me to carry it to work today, where it was used to open the strapping on boxes of A4, cut open my chibatta and file a rough nail lol.
OK, one last bit of waffle....
Your average period Solingen steel vs the average period Sheffield steel. Which is "better" and why?
