Personally, I think the step-thru punch packs tremendous power, if done correctly.
In karate, so much of what it means to do it "correct" is based on the context of the hyung. Sometimes it will have lots of power and sometimes it will be much more subtle. If the application is seizing and smashing, then the technique will have lots of power, if the application is entering and unbalancing, then the focus of power is not on the fist but elsewhere.
I think the way many people do it is incorrect. The upright, stiff, stepping forward into a bow stance and throwing the punch with your other hand chambered at your hip method is, in my opinion, not effective.
I agree. "Punching" like this is not effective. However, consider a few moves in Gi Cho Hyung Ill Boo (Basic Form Number One - Taikyoku Shodan - etc). Low block, front punch, turn. The context of this form is telling one to parry inside, strike with the off hand, hammerfist with the parrying hand and "step in" with a hand to throw ogoshi with the turn.
This technique isn't a separate stand alone technique like it is presented when one does basics. When one is doing a front punch line drill, they aren't necessarily learning to punch. They are learning to do other things.
However, if you are more fluid and step thru and drop into a side horse stance while throwing the punch, it can hit really hard. The fluidity is really important. It makes the technique come alive.
The side punch is still not an effective way to punch. Assuming a hard low stance when it is appropriate to be punching is never a good idea. Stepping into a horse stance completely changes this technique, though. While I agree that one can really generate alot of torque, the focus of that torque is not meant to generate power as a punch.
Think of the context in which you see this technique. I technique preceeds it and that usually contains your striking applications. When this technique appears, the tori snatches the uki's arm and snaps into the bar/break the arm over the extended bicep. If the grab misses, the technique turns into suquee nage.
On a side note, practicing weapons has really helped me with this technique, particularly the chinese longsword. One of the forms contains a high parry followed by a step through, tight spin and an extended stab that requires the exact same torque one uses with the side punch.
The step is also useful for bridging the distance between yourself and the opponent.
Yes, in a number of ways.
I also think the step can be used in the mix of the engagement, instead of as a broadcast technique that is easy to see and therefor stop. But the point is, get away from the old rigid way of doing it and figure out how to be fluid, use the momentum for the power that it generates, and make the movement more subtle and less exaggerated. I'm not exactly sure how to explain what I am thinking, but perhaps this is a start.
I think, perhaps the best thing we can do is stop comparing it to a boxers punch. These are two entirely different animals and the word "punch" does nothing to describe the difference. Just as the word "love" has many meanings and connotations, so too does a punch.
