Dagger for identification and discussion

[Sajen]

I just won this, in my opinion, very nice and also very old dagger by auction. It's 34 cm long and it's said that the blade is heavy. On one side is the blade marked.
I think that this dagger is very old, 18th century?

Any opinion about the age and exact origin? What do you think, it's a hunting or fighting dagger? Pictures from the mark will follow soon as I have received it.
