I hadn’t seen that thread before now. There are some pretty interesting “tool walks” here that are kind of hidden outside general searches through the site.
Watched the video all the way through. Very cool and interesting axes.
The axes are that square-bearded in shape say rough building/shaping to me. Beams and joints. The ones in the video handle juggling and then hewing to make a nice beams. The two axes here seem like they would shear wood fiber using them to drop-cut and not so much lateral cutting for something like felling a good-sized tree. Guess that is obvious though lol.
These are from the following Norwegian site – worth a scroll with Google translate:
Here's a neat site as well that has pictures of traditional Norwegian building axes and tools:
