Yep. Split large pieces of wood with a knife, sooner or later you will break the blade. Even if it's a $350 "bushcraft" knife. If the knife is all you have, that's one thing, but otherwise it's better to learn how to use an axe, even a small hand axe.
Must be inflation, I swear I boutght my axe for about 20 bucks.
