A few hours' practice and a few pressings upon the different parts of the blade under the surveillance of the instructor will teach the recruit the high importance of this lesson. He will learn that in opposing the adversary's sword the strength of the defence decreases from the hilt upwards in proportion, as the Cut is received towards the point; and that, vice versâ, it increases from the point downwards to the hand. The strongest man cannot "force in" the opponent's Guard if the Cut or Thrust be received upon the part near the handle.

Unless true it will become a blow with the flat that would shiver to pieces any brittle Eastern blade. Assuming the vis viva or force of a moving body to be its weight multiplied by the square of the velocity, let us suppose a strong man cutting with a sword weighing 4 lbs., to which he can give a velocity which we will call 1, or 4 x 1 = 4: a weaker man who applies double the velocity to a 2 lb. sword will thus produce a momentum of 8, doubling the force of the blow.
