After a lot of thinking and reflecting I have been reviewing joint locks I learned, and have found an issue. Maybe the wonderful people on here can help me out? Just what are wrist locks good for??? I have been trying these on friends with full resistance and I know I'm doing it right, but I find that when the wrist is flexed by way of making a fist the lock becomes impossible. I even had a friend who does the lock well and is much stronger than I am try it on me, and nothing. You just can't force the lock. In grappling matches we tried it, and still simply making a fist counters the lock. Now when being grabbed by the wrist they work at full resistance, but even in matches I rarely see wrist grabs. I have also found many people are immune to wrist locks, and many others are just too flexible for the lock to work properly. Why is such an unreliable technique so wide spread and taught so often. I realize these are great in jujitsu but if I'm not fighting a jujitsuka then just how do I use these???? I never really questioned what I was taught, but I cannot seem to find a way for these to be useful in practical application other than woman defending against an abusive spouse. I have found elbow locks to be far more reliable and practical in sparring ( meaning we actually managed to get the locks in a match from various positions NOT JUST FROM ONE POSITION ) Thoughts?
