Batoning is totally fine, just use a knife that can handle the task (full tang, high carbon steel, well forged: ESEE, Becker, EnZo, etc) and proper wood pieces, not too knotty or hard!
You're...
partly right. Especially when trying to split really hard, knotty or tough wood, your best bet is to whittle a couple small wedges before you even begin batonning. As your blade bites into the piece, tap a wedge in there behind it. That prevents binding, which is by far your biggest enemy.
As for steel selection and build style... the knife in my vid above is indeed full tang, but it is CPM-154 "stainless" steel, and I did not forge it, I ground it from barstock.
Any reasonably good steel with good HT can handle that sort of work. Including properly-designed narrow tang knives made of almost any common cutlery steel. It's just... not... that... difficult. A knife does not even have to be particularly sharp to accomplish these tasks! It's simply a matter of pushing a wedge through the workpiece. That's it... this is not rocket surgery
On the other hand, I've seen many a good sturdy ESEE, Becker, Cold Steel and yes even expensive handmade/customs that were broken beyond repair while batonning. They almost always "fail" right where the handle meets the blade (ricasso/plunge area).
It really doesn't matter much if the blade is full-tang, or narrow tang or even a folder. They break not because the design or steel was bad, but because the person doing the batonning either A) got all buckwild and went to hammering away like a madman, or more often, B) got the knife stuck and kept whaling away at it (usually between the workpiece and the handle, which is almost guaranteed to result in disaster).
Don't let any maker or manu's "hype" fool you!
Batonning effectively and efficiently has a lot more to do with the user's technique than it does with the knife itself. Again, problems come when people get carried away and do it wrong. You can break
any knife if you hammer on it hard enough and long enough. You will definitely break a knife sooner rather than later if you allow your blade to get bound up in the work and continue beating the snot out of it.
