Exactly right, HG1.That bent wrist is something Praying Mantis specializes in, one of many weapons in their arsenal. Other CMA's use something similar & I can tell from experience it is a painful blow. Here's aother opiton to think about, the coiled energy of that bent wrist released into a conditioned palm strike.
Another possibility I learned/now teach (not mantis, but maybe they have something similar), is striking with the end of the arm bones at/above the bent wrist. I call this the oxjaw, although have seen it called other things as well (would have to look it up though, am thinking I saw it in Xing Yi :idunno

Most people when first seeing this believe it's striking with the wrist, when in fact it's anything but: the bent wrist keeps both it and the hand out of the way, and allows for a very powerful strike.You see this targeted often to the chin, solar plexus, groin, and other *upward* targets. But just a note on another interesting application for this strike: if the palm is quickly turned upward, the twisting oxjaw can be brought down and really pack a punch. Likely targets are numerous, e.g., collar bone, shoulder, bridge of nose, temple, hinge of jaw, neck, and even the arms and otherwise not-usually-thought-of-as-targets can get a good reaction.
