Welcome to the forums Olli!
Thank you for the positive id on the axe in that video. The different pattern names being references to the villages and towns where they were originally made/originated is quite interesting.
I was curious about that a little while ago and only searched Uundemaan (no7?) and it seemed to be a reference to a region in southern Finland. That was the only one I thought to search but knowing what you just shared, it now makes sense.
Your English is fine as far as I can tell while reading - better than my Finnish... I have communicated with a couple of guys in Finland about axes but working out axe trades/sales with some guy that sounds like a robot in Finnish probably isn't appealing to most.
Personally, my interest in these is deep but my knowledge shallow. Due to their age, locale, language barrier, and shipping costs they don't show up too often here in the US. Or at least I have not seen one here "in the wild" lol.
Feel free to add any info you think an "outsider" might not pick up about these types of axes, history, handles, or good stories that a native Suomi might know as matter of fact (or anything else for that matter)
