1) added weight as already mention, to help chop through light armor and bone.
2) to blunt the other guys sword, not to tangle it with. In many forms there is a move where you encirle the sword (with the point pointing downward) around your body and then slash. The encircling is blocking with the blunt end of the sword, coming around and then slashing to the neck or ribs or any limbs that get in the way.
