by hitting them lots you will eventually feel less pain this is because you have damaged the nerves so wont feel as much this is useful but bear in mind your body will try to regenerate those thousands of nerves you damaged and when it does some are likely to grow back incorrectly and cause severe pain.
From my understanding this steel shin results from the GRADUAL proccess of creating "microfractures" and then letting them heal. When a bone is injured the body heals it and then reinforces it so it wont get damaged so easily. Doing this without letting the bones heal could cause some severe problems though.
