I used to know a guy who did karate and he said that Jesus T. Christ the Plummer, Scientist, and Proctor of humanity never tapped so he never taps. Aire didn't tap either so I don't tap. Tapping is for quitters and sinners. Don't be a coward by tapping. I got put in a kimura once and it hurt like hell but I did not tap because my master said to never give up. I used my sand from Coon to defeat my opponents on Saturday and they tap out from the Coon sand crushing there arms and legs. I don't tap like a *****.
Lot's of rambling answers for a simple question. Yes the kimura is extremely effective. If you pop some ones shoulder very few people are going to keep fighting. But honestly if you were a grappler you'd already know this and don't go street fighting as a past time. Get to a gym.
Kokoro got it 100% correct. So many people see a move and learn how to do it and then they think they can do it in a fight. The problem with this is the ability to learn to put yourself in the position to use it. its also the finer points of the technique that people dont understand that makes the move ineffective.
As for the question...well have i seen a Kimura used in a fight? YES, have i seen a Kimura end a fight? YES, Have i seen 20 people attempt to use a Kimura to no success? YES (simply because they have no understanding and positioning.)
Most people cannot even put a technical Kimura lock on and have it effective enough to worry the other person in a street fight anyway.

EDIT: @Danny - sorry i disagree, you do realise you can use a kimura lock from a standing position? this allows you to direct the person in the position you wish for them to go such as escorting them from a club. It also allows you the ability to use that person as a shield against multiple attackers. I seen my brother do this against 3 guys when he was a nightclub bouncer so it does still have a practical use against multiple opponents
The kimura is very painful and often taps me out when I roll.
The problem is, its most effective on the ground. Which means if there's any possibility that more attackers might attack you, then you wouldn't want to go to the ground.
That being said, the Kimura is a joint lock that is slowly applied. Fastly, all joint locks are joint breaks. If you broke his arm with one, no he would not be able to keep fighting. If by some miracle he was, he would not be very effective with a broken arm. This is the time to do a flying roundhouse knee to his temple. That will knock anyone out.
It's extremely likely that your opponent will stop fighting after you dislocated their shoulder. I can only see them fighting after that if they're on some form of illegal substance, such as meth. Still though, it's not a bad idea to have a backup plan. Lucky for you, after a bottom Kimura, usually a triangle is open (if in guard). If on top for a Kimura (such as side control), then there's multiple attacks you could pull-off, or just start striking your opponent.
About the same chance you'd ever get to put a kimura lock on him.
Here is one thing I can tell you for sure. You can pick a technique that way, call it the best, and never ever be in a position to use it.
Your martial art must manifest all by itself when you need it. If you need to think about it, you have not got a martial art, just a group of techniques you will never have time to use.
edit: @ Mark: don't know why the kids gave you all the TDs, your answer is right on the money.
It is only as effective as the person using it. Little skill there is a little chance it will be effective. A person with much skill and being in the right position has a great chance of using it effectively.
I think that a lot of things would have to go wrong for you in order for you to be in a position to apply it.
That said, even if they continued to fight, you could render their arm useless if you applied the technique explosively:
Depends on the person you've got it locked on. I had one locked on a guy in training once and to get away he just stood up. Pushed up with one arm and stood up with 90kg (200ish pounds - my conversions aren't great) of me on his back then shook me off like I didn't matter. It doesn't matter how good your kimura is if you can't keep your target trapped so they're forced to keep suffering it.
Whats the chances that your oppenent would continue fighting
it works exstremely effectively if u are good at using it.. only 2 problems is if there is more attackers they'll mess u up when u try and do that.. and also ya before u use a devastating move like this please please please try and leave the situation first, cause if u use this and break someones arm u could do some serious jail time.. so ONLY if there is absilutly no other choice and they start fighting u first.. but yes why would they teach this if it didn't work lol
in real fighting that hard to use because enemy always move puch and kick, i prefer do puch and kick too direct to vital object than must grapling
A submission is for subduing. For self defense, you would want to commit to snapping the arm, otherwise you're just immobilizing your opponent for as long as you're holding him. The "tap out"/"I give up" method doesn't really apply to real life situations.
One of the first rules of self defense isn't to "bout it out". You want to get out of the situation as fast as possible. Purposely going to the ground just to hold on to your opponent isn't a great idea. Knowing how to deal with being sent to the ground is a good idea, but a submission like in a competition isn't a great idea either.
The goal of many joint locks is truly to break bones. Unless you do this, it's best to train to do something else.
@Jim R: Thanks for the compliment. Anyone who thinks I'm wrong is clearly someone who has no real life experience or a mind for realistic situations. As much as I've ragged on ground fighting and sports in self defense, most of the people who gave me a TD probably never even read my whole answer, if any of it.
100% chance that he would continue fighting. He is still conscious and standing. That's why KO/leglock/chokes are the most reliable. Lets say you break his shoulder but he has a knife in his pocket and one working arm...
the problem isnt the technique as much as knowing what you are doing during the the incident.
you people are fixated on pulling off such and such move. what you fail to realize is the move is only good if you are in the right position and offered the opportunity to utilize it.
thanks for the thumbs down kw

ya sure kw what ever floats your boat girl,
