light skill vs strength

could be due to weight classes.
When you look at it, getting a line drive to the chest is striking with tremendous force.
Two 170 lb guys punching each other might not equal that force.
Now, take two Kyokushin guys, one 170 lbs, the other 250lbs...you might find different results.
just sayin..

There were no weight classes in Kyokushin till about the mid 90's.

point taken-however it does not negate the fact that you can crush a trachea.

Sure you can, but not like this:

. One is jin jih (arrow fingers) designed to collapse the trachea. This move is not likely to work by itself but only follows a technique used to drag the opponent's shoulder in order to cause neck extension. The preceeding move does take a lot of power training but the jin jih itself is a light flicking move that relies on the allignment of bones in the hand and arms to deliver the force.

Sure you can, but not like this:

Really? The mass of a human arm moving at high speed is not powerful enough to bend a little cartilage?

I must have been misinformed.

Yes you must have... or maybe not.

Please point to a clip demonstrating the technique you are talking about.
