In a German forum I read about this issue, too
Interesting that splitting wood is a major issue on English/American dominated forums. Seems the outdoors folks have differing priorities.
Helle has reacted to this phenomenon by adding an Americanized design to their line giving up the traditional Scandinavian rat tail tang design.
Finally the closest relatives are the hunter, eggen, fjellkniven and the folkekniven as I can see it. So if the (IMO emotional only) aspect of a more massive tang like at the Temagami feels better there's nothing wrong with it. Maybe except the price. The others have significantly less steel in the handle but still enough to do even batoning. And you pay less.
So if you don't hit the handle with the baton and limit yourself to logs under 2 inches and avoid knots or real hardwoods any Helle should do fine!
Remember batoning applies VERTICAL forces to the blade.
Measure: blade is about 20+ mm and spine 10+ mm high.
This IS massive.
Avoid lateral forces as the blade thickness is just average 3.5 mm only.
If you respect And observe these mechanical features you'll add a lot of life expectancy to any knife!
the sharper your knife - the easier your life!
see you at the Fällkniven forum
