This is a carpentry axe and would be a shitty choice to do carving. The cutting edge of the axe from the video has been unwisely altered by giving it a radius. The edge must be completely straight with sharpened to a point heel and toe. You can see this axe was forged by the smith Skog, the second of the Hjärtum blacksmiths, from the "S" stamp on the poll, and it seems his axes are thicker and heavier than the axes from the latest smith although his axes are highly sought after and command high prices as KK has pointed out. Still, it comes in 4 different sized versions. The form and use aside, probably the most critical aspect of this axe is the particular skill and technique of the forging and tempering process and to a lesser degree the laminated blade. These things cannot be copied although the company Wetterlings tries to pass off the carpentry axe it puts out as Hjärtumyxa and its rip-off of the name should be understood. Also the firm Gränsfors Bruks manufactures a similar carpentry axe, nowhere near the quality of the true version but at least they avoid the plagiarism. Also there is a Neeman version. Still like I point, out only the Whetterlings company goes so far as to blatantly lay unjust claim to the original which is a shame.
But the good old Hjärtumyxa is a very specified tool used in carpentry, to cut and fit joinery for example, particularly in the kind of, lets say Scandinavian log construction. The straight cutting edge and flat grind of around 10 degrees each way make it more difficult to use than a blade with a radius because more of the blade is entering the cut all at once - I'm just referring to my experience with the Gränsfors version I'd had till this week but have sold to help pay for the Hjärtum I'm getting sent down - but also more capable of making accurate cuts and for paring to get the right fit.
