It was all part of one statement, it weren't 3 arbitrary sentences unrelated to each other.
1. Had you imbued your sword with Haki, your swords would not have broken
2. You should treat any nick on your blade as a mark of shame
3. Every weapon can become a black blade like mine (context of this sentence?)
4. No alcohol until you've mastered that feat
If sentence 4 referred to 1 and 2, there would be no point in even mentioning his black blade. :D
