Re: Practicing Wrist Locks With a Karate Instructor
The karate guy sounds like a good guy.
If you're trying to 'teach yourself' wristlocks, it might be useful to know that 'making it hurt' really isn't the main goal most of the time, and isn't really enough for you to be able to say it's 'working'... just causing someone pain is not always all that effective at getting them to do what you want. The more upset or worked up someone is, often the more the adrenaline keeps them from feeling the pain (or sometimes if they feel it fully it makes them mad or confused or motivates them to try to hurt you to try to make you stop)
I once tore a toenail partly off and didn't notice until I saw the blood (it hurt like crazy about five minutes _afterwards_, but not at the moment). The first time I got an injury from a wristlock (tore something, took a couple of months to heal completely), I didn't realize it until after class. I broke a wrist when I was fifteen and didn't realize there was something wrong until I went to open a door. These are very common experiences, it's not just me. I was even talking to someone recently who dislocated a shoulder, which is generally known as a particularly painful injury -- yup, she didn't notice it until someone told her it looked funny, didn't feel all the pain until the next day.
So no, 'if he's tapping' isn't really a good way to know if you've got it right or not. It's more about being able to move them where you want to move them, keep them from attacking you, etc...
Maybe I misunderstood the 'stooges' remark, but unless you're a security guard or something (in which case a proper training course designed for that is what you need), if you're having conflicts at work this is the last thing you need -- you need something more like verbal conflict resolution training, or a more supportive boss, or whatever. Otherwise you'll just make things worse and get charged for assault or fired for brawling on the job.
