Russel -
I can't read it all, but here's my best guess. The first name is Juho (pretty sure of that) the last name looks like Seppala (there were several of this family who made puukko), the last word is Kauhava (major knife center in Finland). I would guess pre WW II era.
Jens -
I can't make out anything on yours expect the town Kauhava. Sorry. I would guess about the same period as Russel's.
Here's the link I use (have to register) that has a great Scandinavian knives forum. One of the members can surely read it accurately for you all. It's mainly a knife makers forum, but the folks are very good and kindly will translate old makers names if they can. Please post any responses you get.
