Practicing karate for personal safety requires a holistic strategy that covers far more (and sometimes the opposite) than the skills normally practiced in the dojo. Even if the practical methods taught are contextually aligned and effective for civilian self-protection, these still only represent a small part of a viable personal safety game-plan, as they tend to focus heavily on the last resort of a physical response. Of course, there are numerous options available before the requirement to go physical that unlock initially through the ability to maintain a healthy level of situational awareness and perceive potential threats before they may become a significant problem.
Now that's what I call a question...
What is correct form?
Ask ten people and I expect you'll receive ten different answers!
In fact, the reason why we have differences in the performance of kata across style is ultimately down to what is considered 'correct form', which is in essence a human construct.
After all, karate doesn't really care what style it's from!
So let's take this idea of 'correct form' and explore what it may actually mean...
Please check out this incredible playlist that features a series of short interviews with some of Okinawa's most respected karate masters...
These genuinely heart-warming interviews have been beautifully produced and serve to create a very valuable record of 16 teachers who not only have direct links to the pioneering masters of our past, but who have also contributed greatly to karate's continual evolution and inspired so many to find passion in this incredible art.
Following the ongoing debate and controversy over the Internet surrounding the practical purpose of Hikite (pulling hand), I thought I would offer my own take, which doesn't suggest any specific application per se, but instead covers what is in my opinion, a far more essential understanding of this concept in action.
For me, in order for the physical expression of karate to become both holistically effective and integrated, we must look at the classical kata choreography according to its most essential elements. Regardless of any particular combative purpose (which due to lack of historical evidence is always going to be a product of reverse engineering based on informed opinion), the expression of universal principles that govern karate are entirely dependent on how we move as a human being. That is really our only constant.
If you practice or teach karate as a means of self-defence, then I think it's crucial that you make a conscious effort to explore common traditional practices for aspects that are counter-productive to this goal. I'm not saying that we should eliminate these altogether (as they may provide other values), but it's important I feel that we are proactively mindful of where they may contextually sit.
One of the issues with traditional karate practice in terms of training for self-defence is that of environment. In reality, the application of any self-defence effort will involve interaction with either a real or potential violent threat to the safety of you, a friend or loved one. And the environment by which this interaction takes place may be totally unpredictable and critical to the outcome. Furthermore, that environment is likely to be in direct contrast to that of the dojo.
Here's an excerpt from My Book on the application of Naihanchi Kata for self-defence that discusses environmental considerations...
