Yes many have no use for board breaking, and for a number of reasons. Nothing wrong with that.
Yes many places use gimics and props for show, and yes there are a number of attention-getter or attention-needer showoff types.
Pine boards don't always break. I remember one TKD test where I hit a single one-incher with all my might and the power was just right. The board did not break but I did send the two board holders reeling back quite a few feet, almost into the visitors as I followed through with the technique. It WAS a real good strike and the visuals I created were much more impressive than if I had broken the board. When I went after that same board a second time, it was afraid of me because in my my mind I could hear it crack before I made contact, and it disintegrated when I nailed it the second time.nearly everyone can break a pine board that is not too thick and when it is placed properly so they can safely do so,after being guided and shown how to do it.
And then there are two-inch pine boards which are nothing like two one-inchers. They are HARD to break, real hard. I had to break two of them with my hand to pass a 2nd dan TKD test but only managed to break one on the first try. The first try was all there was because the throbbing rush felt like I punched a cinderblock wall with everything. That was the toughest event I did in all my MA life, because even though I was decent at breaking, maybe better than average at that time, I sufferred a terrible and shameful humiliating defeat in front of all my friends and collegues as well as the group of onlookers that I wanted to cry as I folded and gave up. But I grew out of it and that event, as distasteful as it was, helped me mature even more into the martial arts.
Most TKD board breaking, BTW, is serious stuff. At least in the dojang I've worn my belts in it has been.
But boardbreaking is fun too. I used to break a lot of boards with a 360 deg spinning wheel-kick to head level. The preipheral speed one can generate with that kick is tremendous. Eddie DeCosta, my first Uechi-ryu master taught me that kick. HE was phenomenal.
Breaking with the elbow is fun at first because that one also lends itself to snapping a thick stack of boards in half too. One wouldn't think so, but there is tremendous power in the elbow and to be able to generate that power is awesome.
Forget about the clowns who break, halford. There are clowns in every walk of life. I don't even think about that abberation. You just have to turn your head sometimes and look for the good in other people.
I have seen, many times over in my travels, halford, people who had sucky kicks with not enough strength go through a wet paper bag take some board-breaking training and in a very short amount of time develop better-than-average kicks.
Uechika just don't do boards barring a few exceptions to the rule. Those same people often scoff at board-breaking as well. Why? Lack of self-esteem and lack of self-confidence of their own karate system -- and a subconscious fear of failing. Remember, if you are afraid to fail, you WILL fail. Breaking a few boards, and they don't have to be set up in stacks, either, in the right context can exorcise that fear from the soul.
Get out there, break a few boards, have fun, get it over with, say you've done it, and if you don't like it just move on to something else.
