Carrying a knife

The knife is a simple and ancient tool of man.

The knife can be a fearsome weapon.

At distance of 21 feet or less the knife is more effective than a firearm. Properly sharpened a knife will pass through flesh like air. The blade cutting arteries, veins, tendons, nerves.

In use the knife is not just stabbed in, but stabbed in then cut left or right through the vital organs and major blood vessels. This is instantly debilitating and death follows quickly.
