Are there any super short quotes or proverbs likening honour to a sword?

I need it for my story pick-up line in this website I'm posting it on as the title is 'The Honour Blade'. However, I can't find any. I'm doing research but to no avail. Please help me and I will be endebted to you forever! It had to be super short though otherwise it won't fit in the space they give for pick-up lines about your story. Thanks a million in advance!
