To go along with this, on page 494 of both the US Kindle and hardcover editions it says:
"I'm telling you, I'm dangerous. Sure, I can crush this little rebellion, bathe Oathbringer in some blood. Great. Wonderful. Then what? I come back here and lock myself in a cage again?"
I wasn't sure if I should report this as that's an idiom that could still exist in the world considering not all blades are shardblades, but it seemed less applicable to Oathbringer.
