I don't think the speed of the wave is a moot point at all. To say you'll have your knife out and ready for an SD situation is just not true. While awareness is key to self defense you can't say you'll be aware and see the attack coming and thus have your blade at the ready. Alot of fights or attacks start before the victim has realized. Infact this is exacly how criminals want to start their attack, they will often use distractions or a ploy to put themselves in an advantageous situation where you are caught off guard. This might be asking directions or for a lighter. What are you going to do draw your knife every time someone on the streets asks you a question?
I'm not trying to argue with your points other than this one. Craig Douglas included the wave on his Spyderco Pikal knife for the exact reason many attacks you won't notice until you're being gripped up. The ability to draw your defensive knife under surprise and stress is a cornerstone of many modern knife based self defense systems.
I agree with everything you said. However, you misinterpreted my point, which is completely my fault.
My attempts to detail everything always result in my point being totally garbled.
What I mean by deployment speed being a moot point is that, from knife in pocket to knife oriented in hand for use, the speed is ultimately the same as any other opening method, in real world terms. The knife community tends to get really hung up on single qualities, like deployment speed, steels, pocket clips, etc., instead of putting things into realistic overall context.
I train and instruct combatives and edged weapons for a living (including MBC for recognizable crwdibility). We prioritize weapon drawing and deployment under duress for obvious reasons.
I'm the only Emerson guy there. I've drilled all the opening methods to death, so I could choose the best for myself. So have the other instructors. In the end, pocket to ready speeds were pretty the same across the board regardless of opening method. Of course, a user's skill level is going to heavily dictate individual results. These are mine.
I'm a fan of the wave because it's convenient and reliable for utility. Not because it adds any real world usable speed to my defensive needs.
I'm mincing words here, but I would label the benefit of the wave EASE. Not SPEED. With sufficient training, any opening method can be made lightning fast. But that takes time, dedication, and a little talent. The wave offers this without the need for extensive drilling of the technique. Anyone can do it.
As with anything in life, the user dictates the results. Not the item.
While we're at it, an interesting thing I've NEVER seen anyone else bring up is how a wave can screw you under certain circumstances. If you're on the ground rolling around, the wave can actually prevent you from getting your knife out of your pocket, as the knife needs full clearance to work. In practice drills, this problem happens consistently, usually in worst case terms, with the blade partially open in the defender's pocket as he/she writhes around. Very bad. But also a good outcome to be aware of.
Back to that whole "awareness" bit again. Applies everywhere. And, while an extended debate is not my interest, I'll counter your initial argument here:
When CORRECTLY UNDERSTOOD (key) and practiced, proper awareness absolutely CAN prevent any attack. Each of your examples can be traced back to failed awareness along some point before a conflict. Expand your thinking and run down those scenarios in your mind again. Crap happens when one slips for an instant and loses awareness in some way. Sounds odd at first, but chew on that awhile. Really think about it.
Finally, and stating again, I'm simply being objective here. I'm a big fan of the wave. Probably more than most. Because I understand exactly what it is, and understand its limitations and strengths. Also probably more than most.
BTW, I realize my blunt tone can come across certain ways sometimes. I'm just here to learn and discuss. Nothing I'm going to read on the Internet is worth getting worked up over.
I hope it's the same for the rest of you!
Anyway, hope that clarifies some things that were brought up. Let's get back to the topic of why Emersons rock.
Thx.
