I was considering the emerson cqc series. Can I open the emerson cqcs with a flick of the wrist? I don't plan to have it clipped on, so the wave feature is pointless for me.
In a SD situation the second best thing after having a knife with you, is being able to access it FAST! You say that you don't plan to have it clipped on. Have you ever considered though how you plan on carrying it? One of the factors that you need to consider seriously is your every day attire. If you are working in an office and you are wearing a three-piece suit, then I think you will have a really hard time trying to hide a BM RUKUS. Then again, if you are wearing slacks thats a totally different story.
I am looking for a knife preferably with a black blade with an excellent grip and as close to 4 inches as possible strictly for Self Defense purposes.
I agree with ELBIOS666 (post #6), kayak101187 (post #10) and mauiblue (post #26). They dont get faster than this. All this IF there is no problem for you carrying an automatic and you strictly care about SD.
It can be more than 4 inches.
Just keep on mind that while larger folders will offer greater reach they will be more unwieldy. That, in a situation where fractions of seconds count, to me is not the best deal. On the other hand, if you are thinking of engaging in an O.K. Coral type of altercation then, by all means, a longer blade will be a better choice. However, I strongly recommend that if one is given the opportunity to leave then beat it! I find wisdom in nelsonmcs opinion (post #14)! There is nothing wrong about doing it IF you AND your loved ones are given the chance; as a matter of fact it is the best option.
It is essential that I can easily open the blade with a flick of the wrist under stressful situations.
In a stressful situation IMHO you should not try to open the blade of your folder by wrist flicking it. If you do try it chances are that the centrifugal force generated might make you lose your knife altogether. Remember this: we are talking stressful situation here (and I really hope nobody finds themselves in such a situation). That means your heart will pound faster, you will lose your calmness, fear will start to immerge along with doubts as to what is the best way to deal with the situation at hand. You wont have the luxury of thinking clearly. Now, take all these factors into the equation and ask your self: do you really want to try the wrist flick method?
The blade shape must be designed for SD purposes.
In my opinion this sentence alone could be a thread in itself. For instance, I can easily see a thread with the title What are the configurations / characteristics of a blade designed for SD purposes?. Having said that, I think it becomes evident that this parameter needs to be defined first and THEN be dealt with
I don't know if the spydercos open that easily.
Some of them open faster than you can possibly imagine! In line with this, I find rusty edges comment (post #16), as well as, Joe Talmadges (post #33) very prudent.
