Yikes! Yes, I can see that if you are intent on stabbing someone you might be discreet about it, rather than give someone warning. And that showing a blade might bring about the desired result (someone leaving you alone, or scaring them), without the need to follow through. But there are certainly plenty of videos referenced here in the journal of people overtly displaying knives and then going on to use them that I wouldn’t want to rely on that adage.

That must have been horrendous. Poor chap!
