No it's not just a deflection... this time he is mostly not wrong. He just sucks at explaining things. Zen, how many times have I told you? Less is more.
I know, I know. I'm trying though.
So the basic concept is: you can meet the punch at a slight angle, or head on. If it has a slight angle, it will deflect. If the punch hits head on, it has a chance to break a finger... maybe fracture a knuckle. The latter is less likely. The the knuckle has the backup mass of the bones behind it, if the punch is thrown right, so it may not fracture. But it will hurt the guy's fist a lot.
But if you meet one of the fingers with your elbow... big bone meet little bone. If the fist isn't totally clenched, you can break a finger. It's not like it will happen every time, but even if it doesn't, that finger will be in a lot of pain and make it much less fun for the attacker to punch with that hand.
As for the one he's talking about with the elbow moving downward, you can use it on a guy throwing an uppercut if the guy is trying to throw it from just a bit too far away from you. I actually used it on someone who for some reason decided that a rising front instep kick to the face was a good idea. And then felt really bad as they were limping for the rest of the class.
I cannot say it better. Thank you for being so concise in explaining it.
As far as using it for a straight punch, I don't like it, as for the most part, you are redirecting a punch downward and into you. Zen, if it is working for you, likely your partners aren't committing to their strikes enough to where you would see this as a problem... which from what i remember is likely.
In some instances this is probably the case. I mostly have small size (smaller surface area) and greater speed over people I go up against. Without that edge though, I concur, it is a strategy which carries high risk, especially when its utilized to try to control the hand, or deflect the punch.
As far as using the elbow against a straight punch to the throat or head (Zenjael, this is mostly for you)... don't. It leaves your ribs wide open, and presents a fantastic opportunity for a kicker to get you. In fact, a basic sparring combo is to purposely straight punch at the head, then if they use a traditional high block or their elbow, roundhouse kick to the ribs.
I have noticed this. I took a... unorthodox route to address that vulnerability. It is difficult to describe without a video clip, but if you look at the one of you tube, you've notice how often I'll do what I call arm rotation. I do it by choice normally, and it's either to generate power, balance, or momentum through my arms. When raising the spike I would, most likely (if not sticking with just Krav Maga) lower the back defending arm toward the hip. It's enough to ward the ribs and still have space to block a strike to the now more vulnerable space you've moved the hand from.
But... I also favor a knee in conjunction with the spike if it's necessary to defend the ribs. I've found one can normally tell when a spike will or will not work; I can think of a number of times I've used it in a match where I never had the opportunity to actually deflect a strike, but it still worked very effectively as a ward when timed properly.
I suppose if I executed the spike, and it was a wasted technique I would try to salvage the wasted flow of momentum and attempt a kick to whatever limb had either been extended and I missed, or was being retracted. Luckily 18 years of WTF TKD snap-kicking also gives speed towards ones legs. Especially when short. Sometimes it's a curse; but when it comes to martial arts, I've noticed they seem tailored to smaller people. Oh Do Kwan Tae Kwon Do, I was taught is really only executable by people 175+ pounds, or over 6 ft. I can do the mountain stomps, but it's undeniable that what I do is not the same as what I could if I had another... hmmm, 65 pounds.
So don't. Just check with your hands, or better yet, slip the punch and drill the guy.
I agree. But I feel in a real situation, or serious struggle in a match, that against someone who is of comparable skill or legitimate threat I would not just throw the spike, and reset. I'd throw the spike, and whatever opportunity is presented from its utilization I'll take advantage of, as I see it.
I mean, practice is what is for experimentation. Sure, I agree with everyone that knife disarms are better done with the arms than with your feet (through kicks... movies) but that doesn't change that learning how to do it, and the theory behind it, might not in itself be practical toward other applications in martial arts.
I'd never do a 720 kick in legitimate combat- but I don't mind if the person has given me the degree of control to allow me to execute it on them while we're just sparring. I think any real martial artist has won their fair share or tournaments, and lost. They have reffed, and judged, and have come to realize that those competitions are for the young, and prideful, and that what really matters is how the art can guarantee one's survival while keeping the art itself intact while being used.
That's partially how I see it, hence why I'm willing to experiment with risky, even untrustworthy techniques. I might get hurt for it, but at least I learned my lesson, neh?
And I am speaking of a boxer guard. I favor that when I realize I'm against someone who will allow no room for err. It's... I suppose the best for when preferring attack. Kinda makes sense now that I think about it, even the earliest boxing, Pankreation apparently favored the stance we know as 'fighting'. Mayhap that security it offers is why it appears across so many styles? I delineate though.
To Gnarlie: I'd say it's risky, but while I feel silly writing it, what feels normal to me in executing techniques, is of a speed that is beyond most people. I rely on this, and I suppose it is a crutch, but I feel that perfect technique can offer equatable destructive power as a sloppily thrown but full force thrown technique, and if with sufficient speed most of the time people do the work to themself, and hurt themselves off the deflections. I aim for efficiency as well, and targets which are debillatating.
I work in a donut shop part time, and we get flies, especially as I live in Northern VA and its summer, and I practically live in what's a paved over swamp. For practice I enjoy catching and releasing them, repeating. This isn't to say that I'm some kind of zomg-epi awesome martial artist; lots of people in my family can do it, it's in part why we're so good with firearms, though I suspect traces of redneck in the blood may have added to that. The point is that I rely on that kind of reaction time and speed in sparring, which to a degree cancels out the risk; because I can read people, and react to what they intend to do, oft before they even know they are going to do it, I can also time what is necessary as a counter, as they execute their techniques. I.E, if I use the spike, it will be when appropriate, and in addition, to inflict damage, and set up for a follow up from either arm... usually. Theory. Theory. Theory. It doesn't always work out. We know this about every technique.
Sorry for the fluff, this thread has me particularly excited today. Somebody who normally disagrees with me, actually agreed for once. That's a nice feeling ^_^.
