Randy,

Holding the Cha, point toward the crook of the elbow, the defender sitting in the palm of the hand, the long point should JUST cover the entire forearm. Mine are actually about a 1/2" too long.


Also, in our art at least, these are the proper way to hold the Cha, to avoid any unnecessary removal of fingers.
Closed (holding the Cha this way, you would use the long point to defend, as in a forearm block, and would strike with the Soveriegn, or pommel):


and Open for point strikes (using the Cha this way would allow traps of bladed weapons, and a quick twist of the wrist would break or disarm the blade):
