Sorry doesn't cut it. You seem to be ignoring any advice for those who can't CCW/firearm and by the way this thread is about knives.
So what is your solution for defending without a gun? Fromwhat you have said I'll save you the typing, -you don't have one ....or am I supposed to think you are a BJJ black belt? what? And don't say run away, it doesn't always work,.....
Let's say you are being assaulted and you can't CCW/firearm, what now? I doubt you will reply because you DONT know what now. Now that I have taken your option of gun away you are a fish out of water, a bird who has flown too high where the air is very thin....what now tirod?
I know what I would do but that's not what I am posting about, I want to know what you would do. I have the experience and methodology. I would be fine, but I doubt you would be. The 2 times I used a knife for SD, multiple attackers each time, I was not fantasizing. You sound like you think you are God, sheesh! Probably an A/LEO, I'll let everyone guess what the A stands for.
Edit: What you should do, if you want to contribute to this forum in a positive way is to edit out the insults from your post, and re-phrase the information in a respectful manner, I couldn't agree more there are some young bucks out there who need information and positive, informed, suggestions.
You don't 'know' me, and probably could care less [I see that in your personality] but I have nothing but respect for someone who corrects his mistakes, to me that is the biggest shadow in the bunch.
There are a few who can leave the mean streets they live on - and a few who won't take the advice to move out - which is what reasonable people attempt to do when confronted with continuous danger in their lives. Whether actual or percieved, they move to a less dangerous location.
Some refuse to do so and accept the risk. They tolerate it and attempt to manage it. If anything, the posts in this thread suggest 1) take martial arts training and become more capable 2) learn to be aware of your surroundings and avoid the conflict to begin with 3) GET A FIREARM.
I have a CCW license because I live in a state that offers it. If someone lives where it's legally denied, work to correct both the political situation and your personal one. I am very aware that many who live in one of the few "denial" states still do. If it's political largesse, get involved instead of continuing to be a victim.
This is where some resort to "What can I carry as a weapon for Self Defense?" and consider the knife. Buying a weapon for self defense means understanding it's limitations. For CCW, you often can't display it in a threatening manner, must accept that others will get to bully you because you have no legal grounds to escalate, and suck it up because you don't want to lose the privilege.
It's the same with a knife. Pull it at the wrong time, you escalate the situation. You are now the aggressor and liable.
Now the question is - what are you doing to provoke clues that you could be a helpless victim - or at least one easily overcome? Solve those indicators, and quit sending victim signals. Don't look like one, don't be there, don't go there. My posts on the subject - given some research - will show I've said that for years here.
But the gang is on you, despite the effort on your part?
Is there anything in your immediate surroundings that can be used as a weapon? The second most used weapon in DOJ statistics is "Anything Else," and the list is long. Are you committed to using whatever to stop the attack - rock, piece of wood, an off balance opponent's arm, whatever? If you don't have bare hand skills to attack, you don't have the basis to build edged weapons use. Don't take my word for it, ask the trainers who teach it. If I have heard correctly, it's two years of barehand training before an Escrima instructor even hands you a training blade.
Are you in training? If a poster recognizes the need to improve their self defense, the answer is to improve their SKILLS, not pick a third rate weapon and continue living the same mistakes.
Self Defense is not the place for "Why can't we all just get along?" The trainers I had in the military and in civilian life make every effort to point out where our thinking goes wrong, because that's the major weakness to address. Tools and Training are just that - what you do and use after you understand what you're doing wrong. If the process of pointing out mistakes in world view concepts and perceptions in self defense hurt someone's feelings, then the cause is the reader's fault. What was there to get offended about unless it exists? I have no way of knowing - it's purely a very public and revealing acknowledgement on the part of the those who take it that way.
Reacting by limiting the conversation to the rare gang assault and insisting on a pat "Whatch gonna do?" answer ignores so much of what people ARE doing to avoid the conflict - and why is that still being ignored? It IS the correct answer. Not what knife to use.
Don't put yourself in harm's way, you don't get assaulted. Ignore the lessons, well, just hang a fresh meat sign on your chest already. You're not thinking about it, and Darwin's law will correct the situation, unfortunately.
