“In Japan, it was necessary for every man to carry a pistol; but the Japanese [with their swords] invariably got the better of every man carrying one, even when he had it in his hand… …I maintain the great fault in our swords is that they will not cut. Use them as much as you like, unless you have them specially sharpened the night before, they are useless. In the cut, our swords are useless in nine cases out of ten.

Applin, “every cut had severed the member it was aimed at.”
