This reprint of a classic 1901 self-defense article, "Self-defence with a Walking-Stick," is from The Journal of Non-Lethal Combatives, however the part about severing a man's jugular vein sounds sort of lethal.
In the art of self-defence with a walking-stick, the stick is held in the hand with the thumb overlapping the fingers, and not, as in single-stick or sword-play, with the thumb resting on the blade. The stick is therefore manipulated with the wrist -- and not with the fingers as in sword-play -- and the blows are given by swinging the body on the hips -- and not merely by flips from the elbow. In this way blows can be made so formidable that with an ordinary malacca cane it is possible to sever a man's jugular vein through the collar of his overcoat.
