Yes it is. I've broken and seen broken countless knives applied with this technique. Every time you see a review or video with a broken survival knife, it is almost always the case that the knife was broken by batoning it. To survive such use, the knife must have a full-profile tang with absolutely no weak points, a soft temper, and even then it is still inferior to just making a few wedges and batoning those instead. Batoning is just plain dumb.
I've battoned thousands of logs and boards into kindling. Abused some of my knives at 60RC (,so in no way a spring temper) for a a decade or more.
It is a dandy method of making small kindling without packing a hatchet or axe.
I grew up cutting trees to heat my home. Grew up felling lumber, swinging a maul to split wood, and making kindling.
I have no hesitation using many of my knives to chop, and baton...both thick and thin. Big and small.
I've used wedges to split logs before.
I've helped build multi story cabins with lumber I helped cut and shape. I have the knives inherited from my grandfather that he used to butcher farmstead animals. I still use them. I buy similar versions today.
The steel is not perfected. Thinner geometry cuts, but it needs to be sharpened more, and is not as stable, impact resistant, etc.
Super steels. New designs. Classic designs. Thick. Thinner, thicker. Hollow ground, flat ground, convex.
I've got expensive knives, and cheap. I've used $1000 Busse choppers to do all of the things you detest, while grinning. I've used cheap machetes, and axes, and hatchets. I've got a nice Japanese arborist saw.
16 inch bladed old Hickory knives too. All the way to folding opinels.
I like cutting tools. Expensive, bargain. I like them all.
I guess I am glad you've solved all knife related issues for me.
I've used too many steels to list. Tool steels, plain haight and medium carbon. 52100, L6, AEBL, INFI, San Mai laminated, CPM3v, and many many more...
But I'll keep liking what I like. Batonning when I feel like it (with knives strong enough to do it....I would not do so with my hidden tang hollow ground Buck, or my custom stag handled hunter with a thin hollow grind).
