I won't say you couldn't break a stick tang, but I can say I never have.
In fact I split a pile of branches while out hiking at new year using my Marttiini Lynx, not worried once while using it.

I'll second this!
I've got a Issaaki Jaavenpaa Puukko (spelling?) at the boat, and use it for battoning A LOT!!! Ironically the baton I use is the handle of a cheapo hatchet from Wilko's which I keep meaning to convert into a cutting implement (certainly wasn't bought as one - chops as badly used either way round - LOL) but never seem to get round to. Along with a couple of Mora Miki's and a Brussletto Somethingorother (?), I do like a Scandi ground edge for wood processing - though obviously tend to lean towards the Granny B's & Bahco for the heavier work
