Maybe it is because of the sporting application of Taekwondo but it seems that over the years the applied techniques of Taekwondo have become less and less. The full complement of techniques is more than 3,000 yet today in most dojangs we would likely see no more than 7 being practiced
Of course this is an example of people training what they need to train. The 7 techniques that are practiced is enough to see you through your competitive career. When you change the focus of your training however, you shouldn’t work from the same point thinking that the handful to techniques that saw you safe in the ring are equally applicable in self defence.
Yop joomak or hammer fist is one technique that has been left behind. Rarely trained in most dojangs and largely absent in the patterns it is maybe seen as a very low skill technique and one not worth practicing. I have discussed the importance of training low skill techniques before, but I feel hammer fist deserves a little more attention that it currently gets.
For a start it is a very safe strike. Whereas with a straight punch you run the risk of damaging your knuckles. With a hammer fist you can strike full force with little or no damage to you hand.
It is also a very versatile strike. The number of directions and angle that you can strike with a hammer fist far outnumber most other strikes, and in most of these direction you can actually create more power with the hammer fist than other attacking tools.
As well as being a ‘low skill’ technique another possible reason why yop joomak is over looked is it is a softer attacking tool, whereas this is the reason it could be regarded as a safe strike, it may also create doubt in the practitioners mind that it will do much damage. This is true, but we have to also look at how many other techniques we practice that are not knock out shots. We cannot give ourselves over too much to the idea of ‘one hit, one kill’ this leads to a flaw in our training and our thinking. We should always aim to hit hard but we should never think that one strike will do the job. We should be attacking our opponent with a flurry of hard strikes then looking for an exit. Not relying on one big strike and then waiting to see what happens.
My preferred application of the hammer fist is to use it in combination with other strikes. For example, if someone is in front of me and acting in a threatening manner, my hands naturally come up to either try to calm the person down or control the space between myself and the other person. From the ‘hands up’ position a good option is to strike to the nose of the opponent with the hammer fist. After this initial strike, we can then following up with whatever is appropriate. A similar strategy also applies if the person is off to the side or even behind you.
In short then, hammer fist is a safe, versatile, and powerful strike. It can be easily applied as an opening strike in many different situations and defiantly not over looked by someone wanting to develop the practical side of their art.
