Batoning with a knife is one way of splitting wood job, but is not the preferred method in my book. An Axe or Froe is much better. I personally think that batoning with a knife, while a good thing to have as a backup skill, is over rated. To me it seems to be another American import of dubious merit as a principle method of splitting down wood, as some people over the pond are obsessed with it. Some over there will carry a big knife mainly for that purpose, from what I can tell as a 14" Bowie is not the best thing to carry for carving, skinning, trap making etc... You can also cut down trees with a knife, which is also not the best tool for the job, but again is something all of us should have tried at least once so we can use it as a skill of last resort if we need to... Not knocking our American cousins at all but the 'got big knife, must baton wood' theme is something I have come across a lot on you tube. A good axe/hatchet is worth much more when you have a lot of wood to split.
I have broken 2 Moras batoning things, so doing so regularly is not without risk. A few of times a year is one thing, whereas every time you make a fire is something else. The rule of 'do not baton anything more than 2/3rds of your blade length' has worked for me for many years. If you try to baton anything that is longer than your blade length then that is '50/50' chance of breaking your blade from my experience, if you are using your own knife...

. Just my 2 cents.
