Why is the Finn a knife wielding maniac. Sure they beat the Russians, but that doesn't make them collective badasses.
"All Finns carry a knife. Every single one of them. Even that little 5-year-old girl behind you. No kidding! Getting one's first knife is an important coming-of-age ritual for both girls and boys."

That said, my grandfather game me a knife, when I was 10, and all my young relatives as well. Coming-of-age thing
Wouldn't Australians AND Russians do something similar? They have a fitting personality to it
