I bought a 1x12x12 pine board. On the receipt, it is "PINE KARATE BRD" LOL

If we are talking about a 1" thick by 1' square board, it's one of those that is easily breakable. Support it on the edges and give it a lusty whack along the grain with your fist (head, foot...) and it will break. Sorta like crushing an aluminum beer can in your manly hand. :-) gronk, jo4hn

My teacher (Wing Chung) said that it taked about 6 lb. of pressure to break this type of board, about what it takes to break a rib. I tried a

12x12x1 inch piece of ash. It takes a whole lot more pressure to break robo hippy

About as much as it takes to break the bones on the edge of your hand? ;-)

"Breaking boards" are cut with the long dimension cross-grain and are made of pine.

Pine will hurt you if you wimp out . . . most of the battle in breaking boards is not stopping. LONG ago in Engineering Physics, we watched a high speed film of successful and unsuccessful "breaking" attempts.

In an unsuccessful attempt, the board vibrates back into the hand striking it.

But so long as you strike THROUGH, you'll succeed.

Block is similar. Watch Side Kicks (if you must) or any big Martial Arts demo. They break 8" block across the weak dimension.

When they break 12" solid cast footing, I'll be impressed.

Having a daughter who's been involved in TaeKwonDo for several years, I've held many a board in tournements and testings. I can assure you they dont all break easy. When your holding 8 boards (12*12*1) while a 200 lb 18 year old takes 6 attempts to break them your wrists end up in bad shape. The kick that finally breaks them feels so easy compared to the others - got to hit right in the middle and drive through.

And if they miss and crush your fingures.............

REAL men crush them in their butt cheeks.

I was taught that ribs break at 75 lbs. Given what it takes to bust them doing CPR, I'd say that's about right. If it only took

6 lbs, every kid in a fight would have a flail chest. The grain direction is what makes the karate boards easier to break than the usual lumber.

I thought that was walnuts?

I'll be it's wide grained and has no knots. Typical of what they used when there was a demonstration day in the club I attended. I have to admit, I miss the people I met there. Friendliest and most sociable people you'd ever want to meet.

REAL men have a can crusher so they can work faster and get them back to the beer store to cash them in and buy more beer.

The grain

Exactly -- plus speed kills.

That's why I've usually preferred a palm heel. Just don't have time to build up calluses on the side of the hand.
