There sure are some self righteous responses. Funny how the first couple replies can set the tone for the whole thread. Y'all know damn well if he didn't mention their looks, one of the first questions would have been "were they hot". So he tried to make a joke.
He also lives in Maryland where I get the impression people freak out over things that they are taught to be weapons by the idiot box (TV). Plus just about every week there is a thread about how the majority of the public (aka sheeple) freak out over a knife. Some people might be a bit nervous, especially if they have had a bad experience in the past.
He also sounds like he is in the military and might like 'tactical' knives. Not everyone has a wide assortment of knives for every occasion. I have a wide assortment and I carry my favorite knife to weddings, a Rift (baby contengo?). It is his knife to use for his needs.Would a knife with an inch shorter blade be any better around people who have the potential to freak out? It would be one thing if someone's life was in danger and he chose to do nothing. But it was a simple long thread that she probably didn't think about twice. Not a big deal either way.
People like to act holier than thou in certain forums I guess to feel good? Or to try to make someone feel bad? That is until you get to whine & cheese and the girls would be wearing a lot less clothing bent over a water fountain doing God knows what. And I'm sure a lot of you would have no problem expanding on details of the God knows what possibly even providing pictures and video for reference.
I probably wouldn't have helped either since it was such a minor event. If they were hot I might have tried to flirt with them. But the objective would be flirting. If the thread got cut that is a minor extra benefit. Just like letting someone else borrow a knife, sometimes the easier thing is to say no or keep your mouth shut and keep your stuff in your pants.
I would have helped them. I usually carry a small dress knife for those types of occasions anyway.
You carry knives specifically to cut dresses? Bet they don't see much use.
