While a nice puukko, the signature is the standard way most all
Janne Marttiini knives are signed. I have several Marttiini puukko all
signed like this. They started in business in 1928. Now their blades
are made in France and just the knives assembled in Rovaniemi, Finland.
This model may still be in their catalog in current production.
In my 1990's something catalog, it is model #575 I think.
You can check it out at their website (in English) at:
